Under the Sea Birthday Parties for Little Mermaids

The sea is a fascinating place – its beauty knows no bounds! And thanks to films like The Little Mermaid, Finding Dory, and my personal favorite, Ponyo, kids find life underwater truly alluring. If you have a little ocean-lover, an Under the Sea bash is the perfect party theme!

We’ve reeled in some of the best Under the Sea-themed party inspiration. Take a look, and see for yourself! 


 If you're looking for Under the Sea party inspiration that's beyond elegant, look no further than this stunning birthday bash styled by Joy & Co Events. With its spectacular attention to detail and boundless creativity, it will definitely wow adults and kids alike. 

We love how the tablescape is totally sophisticated with beautiful bouquets and potted succulents that bring otherworldy, underwater vibes. Jewelry boxes filled with pearls and seashells have us dreaming of underwater palaces where mermaids frolic and starfish play.

The pastel palette is perfectly on point, as if every little delectable treat has been painted in watercolors. We're loving the combination of seashells and coral with fresh flowers, all on top of a variety of textiles reminiscent of waves and water.

Statues of mermaids and seahorses fill out the buffet table while the sweet treats steal the show.

 Speaking of sweet treats: This is where you really get to appreciate the party's creative styling. Kids tucked into incredibly unique desserts from jellyfish jello cups....

....to oyster shaped macarons, with pearls and all....

....to sea urchin donuts....

....and sand dollar almond cookies.

No party is complete without the favors and the guests here received lovely jars of bath salts....

....while the younger attendees got their very own mermaid wand.

Birthday girl Gabriella celebrated her first birthday with a stylish Under the Sea birthday party planned by her mom. We’re loving the blue, green and purple color scheme. 

The decor was inspired by underwater elements like starfish, shells, and corals. I could totally see these letters hanging in Gaby’s nursery, post-party. 

Here’s a jewelry stand holding starfish clips and sparkly bracelets – decorative and perfect for guests to get their bling on. 

I’ve never seen a jellyfish paper lantern before, but now that I have, I don’t think I can go on living without one.

Here’s an adorable and easy DIY centerpiece: fill a vase with fresh flowers and top it off with a cutout fish… You’re practically snorkeling in the Galapagos.

I can’t even focus on the incredible spread because that backdrop is what mermaid dreams are made of. The best part? It looks easy enough to recreate.

Sea horse lollipops and seashell sweets… 

... and more treats in a gorgeous blue bottle accented with some rope and shells.

Straws with glittery sea creatures... 

... and don’t forget the goodie bags! 

Birthday girl Kaylen’s first birthday party was a gorgeous ocean-inspired bash, with a stunning two-tone color scheme of aqua and purple. Welcoming us is a perfectly frosted tortoise cookie.

Here's a 3-tiered fondant masterpiece, each layer exhibiting mind-blowing technique in cake-decorating.

Give yourself some serious mermaid hair with hair chalks.

For party favors, baby food jars were upcycled and filled with sugar sand and white chocolate shells. 

Hope you were inspired by these ocean-inspired bashes. Will you throw your kiddo an Under the Sea-themed birthday party? Share your ideas with us – sea ya later!
