Hosting a Mermaid Birthday Party

A mermaid birthday party is a unique idea that will make potential guests so excited, that others will be begging to join in on the fun. A mermaid theme doesn’t even have to fit with any film franchise, it can simply be your fairy tale re-imagining of one day in the life of a mermaid. The location can be poolside, but inflatable pools will work as a splash bash for younger children. The party could also be held at an indoor pool, such as the YMCA.


The best colors for a mermaid party are teal and purple. If you carefully consider all of the elements, everything will come together on party day.

Mermaid Party Stationery

Purple and teal are two beautiful contrasting colors that are perfect for mermaid birthday party invitations. The graphics should be bright and colourful, and make the theme of the party readily apparent. Invitations should have the name of the host, date and time, theme of the party, description, and RSVP contact information. These invitations can be printable or sent online.

Mermaid Outfit Ideas

Swimsuits will be essential party attire for the backyard, particularly if the kids want to take a dip in the pool. Mermaid tales are also fun to wear, but ensure plenty of adults are on hand to supervise. Sparkly beaded necklaces can be handed out to the children as they arrive at the venue, and fun rings too.

Yummy Mermaid Party Food

Individual cupcakes are a more popular choice than birthday cake, keeping the table tidy, and minimizing time. Mermaid tails poking out of the surface of the “water” can decorate the tops of chocolate cupcakes. For other treats, fish sticks could be served, tuna salad finger sandwiches, and fruit spears.

Best Party Favors

Besides the dress up ideas such as necklaces or rings, children can be handed gift bags containing party favours. These can contain a toy fish, or other creature from the sea.


You can search around the grocery stores for candy that is in the shape of fish, starfish, or other ocean shapes, and then divide it up into individual packets, and place each one in the goodie bags.

Mermaid Party Decor

Party decor should stick to the purple and teal under the sea theme, though aqua is nice too. Basic shapes such as starfish, sharks, or whales can be cut out from blue paper and then hung onto a long line of garland or streamers, and then used to hang from a gazebo or between trees or bushes.

Mermaid Birthday Activities

You’ll need to choose some fun activities for the kids. If they’re younger, they may simply be happy with splashing around in the pool. Pool games can be set up for older kids. There can be timed swimming events in the YMCA pool, or games where they must hold a ball on a spoon in their mouths, without the ball falling into the water. Be sure to give prizes for the winners.


When you’re purchasing party supplies keep your theme and theme colours in mind. Your mermaid birthday party elements will all join together to make it appear that the kids are having an under-the-sea adventure.
