The Prettiest Mermaid Party Ideas Ever!

Inside: Throw an amazing party for your child with these easy mermaid party ideas!

With 2 boys running around my house, it’s clear I won’t have many opportunities to plan birthday parties for girls.

In the past, we’ve had a dinosaur birthday party, a hungry caterpillar birthday party, and a Star Wars party just to name a few.

Every once in a while, I like to throw together my favorite kids party ideas that are perfect for little girls!

The first one I made showcased the coolest unicorn party ideas and today I’m sharing the next one:

A mermaid birthday party that’s perfect for any little girl! 

Read on below to see how simple and fun it is to plan a mermaid party your girl will love.

Little girls will love the sweet and youthful feel of these invitations.

Older girls may prefer the sophisticated feel of these mermaid invitations.

Whichever invitation you choose, use the color palette for the rest of the party. It’s a simple way to make the whole party feel cohesive without making everything overly matchy matchy.

Party Favors

One of the best parts of planning any party is creating the party favors!

There are just too many great ideas to choose from, so check out a few of the top picks below and create a fabulous party favor your daughter will love.

Kids can’t seem to get enough slime, so why not make this sparkly mermaid slime, package it up in these clear cups and add it to the party favor bag?!

No young girl could resist these sparkly mermaid slap bracelets. They come in a twelve pack and each one has reversible colored sequins!

Does your little girl love to craft? If so, then make these DIY mermaid bath bombs a few days before the party and package them up to hand out to all of the guests.

If you want some candy for your treat bags, use these blue gummy sharks, these Swedish fish or these candy fish to stay with the ocean theme.

Of course, you’ll need something to hold all the fun goodies from the party. These drawstring mermaid party favor bags are perfect for holding a few small treats!

Decorations

A few well placed decorations can have the party venue looking top notch in no time flat. Check out some of my favorite mermaid party decorations.

A balloon set like this one is great for easy decorating since you’ll have a mixture of mylar and latex balloons to spread out around the party area. If you need more balloons, I’d use these pearlized balloons in lavender and baby blue.

If your little girl wants to help decorate for her big day you can make these mermaid paper chains ahead of time and then hang them on the dessert table or along the birthday girl’s chair.

Grab some of this fish netting and these white starfish to decorate the dessert table for an instant mermaid feel.

Add in some blue, lavender, purple and white decorations like these tassels, poms, and garland to make any space extra festive.

Mermaid Party Supplies

To keep the mermaid theme going, use these mermaid scale paper plates and paper mermaid cups.

Or if you want to have a more subtle ocean theme, try these blue and white ombre plates.
