Throwing a pool party is one of my favorite things to do. While I love hosting pool parties for little ones, it is also so much fun to put together fun pool party themes for adults.

Choosing a good theme is a must-have for an adult pool party, in my opinion. Below are 17 of the best fun pool party themes for adults.

Cheers to an amazing pool party season!

1. Movie Night

Have you ever had a movie pool party? Trust me when I say that they are so much fun!

Your guests will love lounging, indulging in some good food and drinks, and enjoying watching a good flick from the comfort of your pool. Having plenty of inflatables available will come in handy for a pool party movie night.

I personally love these pool loungers.

2. Glow

One of the best things about adult pool parties is that they can be at night, after the kids have already gone to bed! A glow-in-the dark pool party theme is always such a fun time.

From glow-in-the dark inflatables and balloons to glow sticks and glow-in-the-dark yard games, there are endless opportunities to add glowing elements to your next pool party.

3. Luau

In my opinion, you can never go wrong with an outdoor luau theme, which works perfectly for an adult pool party. Don’t you love this vibrant balloon arch?

You can add a cute “Aloha” balloon like this to your own arch!

4. White Pool Party

I guarantee that your pictures will be amazing!

5. Barbie

Aren’t those Barbie decorations so cute? This would be perfect for a bridal shower or bachelorette party!

6. Neutral
