A Mermaid Birthday Party

Would you like to throw an amazing mermaid birthday party? Here's is a roundup of all the mermaid-themed party favors, decor and treats you will need to create an incredible mermaid party!


A mermaid birthday party is a thing of my dreams! As a kid, all I wanted to be was a mermaid and suspect that’s true for many little (or big) girls now too. I live near the ocean and I love all things nautical, so dreaming up the perfect mermaid birthday party has been loads of fun for me! I rounded up a few of the essential items you’ll need to create a lovely mermaid-themed day for your special little girl.

Would you like to throw an amazing mermaid birthday party? Here's is a roundup of all the mermaid-themed party favors, decor and treats you will need to create an incredible mermaid party!

Why not start the bash off by giving all the girls mermaid names? You could go with the names of Ariel’s sisters in The Little Mermaid or let your imagination run wild. Collect up some fun costume pieces to dress the girls up and prepare a few ocean-themed games or activities. (Pin the leg on the octopus?)

You could plan some cupcake decorating with lots of glitter and sparkly sprinkles and pearls!

Get started by considering the items listed below. They’ve all been carefully curated from some amazing Etsy shops that I know you’ll love as much as me! (And yes, shameless plug, I listed my shop first. Haha)


What is a mermaid without her accessories?! Give these out ahead of time for the girls to wear at the party or include them in the goodie bags. See more photos of headbands in the gallery, or head to the shop to see what colours are available.

These bracelets are so cute! If you’re feeling crafty, wouldn’t it be fun to include bracelet-making as an activity during the party? These ones are ready-made though, in case you’re not up for the challenge!

And if you’re looking for some books to read to the party-goers or to include in the goodie bags, here is a great list of mermaid books for kids from Jamie at My Lost Book Bag!

There were so many more mermaid birthday party items I would have loved to include in this post, but then it would have been ten pages long. I needed to draw the line somewhere unfortunately.

I’m a boy mom. As much as I love my boys I get the feeling they are never going to want a mermaid birthday party. So is anyone willing to let me plan a birthday for their daughter? Pretty please?!



  1. Can I just how thankful moms like me are for moms like you?! I love to craft, but am not creative in the slightest. I love how this post is curated with all the things that you need to throw an awesome party!

  2. There’s nothing I love more than party planning and you absolutely nailed this! I am loving the hair bands “Mermaid hair…don’t care!” Brilliant! Every little gal would be happy to attend this party!

  3. Beautiful round up! Such a great variety! As a boy mom, it is tough when you see all the cuteness out there for little girls. I feel your pain!
