24 Enchanting Mermaid Birthday Party Ideas for Kids

There’s something enchanting about the myth of mermaids. I guess that’s the point of most myths, to enchant, isn’t it?

A mythical creature who sort of resembles a human except for the seashell bra. And the fin instead of feet. Perfect theme for a birthday party, right?

Ok, I’m not selling this well, am I? A Mermaid birthday party is about the beautiful blue greens of the sea, flowy hair and adorable sea creatures.

Now you’re in, right? There are so many fun ways to party like a mermaid. I’ve collected all the mermaid party ideas you’re going to want for an enchanted Mermaid birthday party.

Plan the Party

My goal for you here is to plan a party that everyone will love without losing your ever loving mind. I want you to have a plan and I want it to be simple. And amazing.

Every party has four elements.

  • Food
  • Decorations
  • Games/Entertainment
  • Party Favors

That’s it. When it’s broken down like that, it’s a lot less overwhelming, isn’t it?

I’ve chosen a select list of ideas for each of those four categories. The idea is you pick a few, I say two or three from each category, and you’re going to achieve that simply amazing party.

Mermaid Birthday Party Food

The food at any birthday party has to meet a couple of requirements. It’s gotta be tasty and it’s gotta be cute.

With our Mermaid theme, cute is a no brainer. There’s tons of cute and easy ways to make food that is right on theme.

The tasty part should come easily with the ideas I’ve collected.

Mermaid Cupcake Pull Apart Cake from Off Beat Bride

I’m going to start at the end with this adorable Mermaid Cupcake Pull Apart cake from Off Beat Bride.

So impressive to look at right? I bet you’re thinking, there’s no way I can do that.

You can. It’s cupcakes and one small cake. There’s some pretty frosting, too. You can totally make that.

You COULD also bring that picture to the bakery and ask them to make it, too. I have no issues with that. Whatever keeps you sane.

Seaweed Dip from The Cottage Mama

My favorite type of party food is when you just take regular food and give it a cute printable with a cute name.

This Seaweed Dip from The Cottage Mama is just good old Spinach dip. You can even store buy that with some chips or cut veggies (which can also get some cute names and printables).

This is the easy stuff that makes up for the slightly difficult cupcake cake, ok?

Under the Sea Punch from Modern Mom Life

I almost always recommend water for as a drink for kid’s at parties. It’s the sugar factor. You can always slap a cute printable label on a bottle of water to make it on theme.

But I’m breaking my water rule for this oh so pretty Under the Sea Punch from Modern Mom Life.

If you make this, serve it like this, in a beverage dispenser. It becomes part of your decor. And just make the one batch. If this goes, then they drink water.

Clam Shell Cookies from Mom Dot

These clam shell cookies from Mom Dot are too cute to not serve at your Mermaid Party. And, don’t tell anyone, but they are actually super easy to do!

Those are Nilla wafers, just jacked up to look like little clam shells with a pearl.

I would definitely invest in the cake decorating tools to get the cute swirly frosting effect and then you will use those cake decorating tools 1,000,000 more times.

“Crab” Sandwiches from The Trophy Wife Style

If you need to serve a “main” at your Mermaid party, then you should serve these “crab” sandwiches from The Trophy Wife Style.

They are winners for several reasons. First of all, Croissants. A sandwich on a croissant is always special.

They are also customizeable. You can do ham and cheese and there are very few children who will say no to a ham & cheese.

But those cute crab eyes are what seal the deal for me on this Mermaid Party Food idea.

Mermaid “Tails” from Ever After In The Woods

There’s something so delicious about salt and sweet. I don’t think I want to wait for a Mermaid birthday party to eat these Mermaid “Tails” from Ever After In the Woods.

Pretzels drizzled with chocolate isn’t super difficult and what I love about these is that if you set them out in a glass cylinder container, they will look very impressive.

It’s always a bonus when your food becomes part of the decor.

You could also make some extras of these and send them home as part of your party favor.

Mermaid Cupcake Toppers

You could if you really wanted to, get pretty frosted cupcakes and add these adorable mermaid cupcake toppers from Etsy.

Mermaid Party Decor

The decor for our Mermaid party is where we can really have some fun.

There are few things prettier than the sea. Blues and greens are my favorite.

Add in some cute sea creatures and you’ve got a beautiful party environment.

Mermaid Backdrop from Tikido

If you’re throwing a Mermaid birthday party and you don’t do this Mermaid Backdrop from Tikido then you, well, you just need to rethink that and MAKE this backdrop.

It is so simple.

Those are paper plates! Simple and CHEAP! See, what I mean? You’re doing this.

This would be a great backdrop for pictures, too.

And if you can’t find those cool irridescent plates, just get some teals, blues and light purple and do an ombre look to make it look like a mermaid’s scales.

“Jellyfish” from Adventures of a Twin Mom

Large scale is your friend when it comes to party decor. So is vertical height.

These “Jellyfish” from Adventures of a Twin Mom serve both of those purposes. They are big and impressive and they are hung from the ceiling.

Perfect for your guests to Ooh and Aah at. And completely simple and inexpensive, too.

Mermaid Inspired Balloon Garland from Garvin and Co.

Balloons and parties go together like bologna and cheese.

Or something way cooler than bologna and cheese.

If you can take the time to make this Mermaid inspired balloon garland from Garvin and Co., you definitely should.

It’s got all the essential requirements for good party decor. Large scale, vertical and not super expensive!

DIY Coral Reef from Press Print Party

Now this is super impressive. Press Print Party has made an entire Coral Reef. This is a lot of work, I’m not going to sugar coat it.

But, wow, the outcome is really something, isn’t it?

There are very simple to follow instructions for each of the types of coral that were made and while it’s definitely a LOT of work, there’s nothing particularly difficult or expensive in this.

Pick a few of the elements if the whole thing is a little too much. Even just a few of these touches would go a long way.

Seaweed Wall Decor from Love of Character

If you’ve got some empty wall space that needs a little under the sea flair, try this Seaweed Wall from Love of Character.

That sounds gross, a seaweed wall, but it doesn’t look gross, does it?

It looks completely adorable. Cut out some fish shapes and you’ve turned a blah wall into a Seaweed Wall! (still sounds gross)

Mermaid Mason Jar Lanterns from Red Ted Art

We’ve done a lot of large scale for the decor, but the small details can have a big impact, too.

These Mermaid Mason Jar Lanterns from Red Ted Art are perfect for a Mermaid party.

Leave out the tealight and they are great for holding utensils.

Mermaid Party Balloon Decor

I don’t think I really need a caption for this do I? You probably want this mermaid tail balloon thing from Etsy.

Mermaid Party Games

Now the fun part. Games and entertainment.

There are lots of options for a Mermaid party. I like a big energy game, a low energy game and a craft for anyone who is really into doing a craft.

Be loose on the games. This is where a lot of parties can go south. Don’t force it. Go with the flow, ok?

Decorate a Starfish Wand from Catch My Party

Here we’ve got one of my favorite things. A two-fer.

You can decorate this cute Starfish cookie wand from Catch My Party with frosting and candy.

Then you can eat it! It’s a snack and entertainment all in ONE! I love double duty.

Treasure Hunt from Rooftop Post

A treasure hunt is an amazing idea for a birthday party. You can put the kids into teams and let them follow the clues.

This Mermaid (and Pirate!) themed treasure hunt from Rooftop Post will be so much fun for the kids.

Pro tip: Think about all of the places the kids might think some of this treasure is hidden and remove anything from that area that you might not want handled. You’re welcome.

Fish Cup Game from Carnival Savers

You are in luck! It’s another two-fer!

This fish cup game from Carnival Savers is part game, part party favor.

This is just like the carnival game where if you get the ping pong ball in the fish bowl you win the fish.

Don’t use real fish as prizes. No one wants to take home a real fish. The other parents will be way less than thrilled.

Pin the Fin on the Mermaid from Pigskins and Pigtails

This is basically Pin the Tail on the Donkey, just done Mermaid style.

Be prepared to have multiple games happening while you are doing Pin the Fin on the Mermaid from Pigskins and Pigtails.

Why? Kids are terrible at waiting in line. Keep them busy with a craft while they wait their turn.

Dig for Mermaid Treasure from Favors.com

I totally, totally love this idea of digging for Mermaid Treasure from Favors.com.

I am completely flabbergasted that this is a game that is set up indoors, however.

Do this outside, ok? Unless there is a hurricane outside. In which case, you probably should have rescheduled your party anyway.

I highly UN-recommend every having a giant container of sand in your home for 9 year olds to play with. That’s what decks are for.

Mermaid Limbo from 365 Days of Crafts

How simple and fun is this Mermaid Limbo from 365 Days of Crafts?

I love limbo at any party. I know I just said that kids are terrible at waiting in line, but the limbo line is like a party in itself!

Crank up some beachy music and laugh at the kids dancing while they laugh at their friends limbo-ing!

What's Your Mermaid Name Free Printable

Need one more party game? This “What’s Your Mermaid Name” printable from Etsy is perfect to get the party started on the right foot.

Mermaid Party Favors

We’ve made it to the end of the party. We want to make sure it’s remembered well with an awesome party favor.

Party favors should be memorable and useful in some way.

And don’t skip it! It’s the easiest way to make sure no one goes home sad. A party ending can be traumatic if everyone is screaming that they don’t want to leave. The party favor eases that transition.

Then you can have your wine.

Mermaid Starfish Wands from One Whimsy Lane

I have to admit that I did not know that Mermaid’s had wands. Is that a real thing?

Who cares? These Mermaid Starfish Wands from One Whimsy Lane are too adorable to not give them out as party favors.

If Mermaids don’t really have wands, they should.

(I’m aware Mermaids aren’t real and therefore can have whatever we choose to give them. I’m also aware I might be a little Mermaid crazy at this point.)

Mermaid Bubbles with Printable from Spot of Tea Design

I love bubbles as a party favor for a little kids party.

I love that they are something the kids can use when they get home and are missing being at the party.

I really love that these bubbles are right on theme due to the adorable Mermaid printable from Spot of Tea Design.

Seashell Madeleine’s from Baker’s Party Shop

I don’t normally like to send kids home with MORE sugar, but these Seashell Madeleine’s from Baker’s Party Shop are too pretty to leave off the list.

Here’s a little secret for you.

You can just use store bought Madeleine’s for this. I won’t tell anyone.

Pinky swear.

Beach Bucket from Growing up Gardner

This is the best party favor idea of the bunch here.

A Beach Bucket, as we see from Growing up Gardner, is the perfect party favor for a Mermaid party. It’s on theme.

And it’s totally useful. When my kids were still little, I was always looking for a bucket to take to the beach. The other moms will be so excited.

Ocean in a Jar from Chickabug

This adorable favor from Chickabug made it onto the list despite being full of candy for two reasons.

  1. It’s adorable.
  2. There’s a mini mason jar involved and those are always appreciated.

If you’re going to give a bunch of candy for a party favor, it better be super cute and on theme and if you can get it in a useful container, then I’m a happy party planner.

Mermaid Bath Salts from Evermine

I don’t have to tell you all the reasons I love these Mermaid Bath Salts from Evermine, do I?

I mean by now, you know me.

Let’s just see if you guessed right.

They are adorable. They are useful. They are on theme. They are in a useful container.

If you got all four, my work here is done.

Etsy Bonus Idea!

Mermaid Bath Bombs

If you go with a bath product theme for your party favors, you might want to snag these Mermaid Bath Bombs from Etsy!

Party with a Plan

Okay, you’ve got the plan, time to make if happen!

Pick a few from each category and plan an Enchanted Mermaid Party for your little!
