Every great party needs a clever theme, so we’ve pulled together a list of the most unique 3rd birthday party themes for you and your big boy or girl to choose from.

Many of these ideas we brainstormed ourselves, so you can be the first in line to bring it to life (send us some pics if you do – we’d love to feature them!).

Creative Unisex/Gender Neutral 3rd Birthday Themes

We have to admit, we’re a sucker for a good pun and play on words (see our list of 1st Birthday Party Themes and 2nd Birthday Party Themes as proof). So we scoured the web and put on our thinking caps to find the best (and newest!) 3rd birthday party themes that include “three” or “third”.

The ideas below can be used for either boys or girls – scroll through and see which one is the perfect fit for your big kid (and keep scrolling for more girl and boy inspired third birthday themes too!)

Adios Dos

This fun theme literally says “goodbye two”, and is the perfect way to celebrate moving onto year 3 with a bevy of colorful cacti, llamas, and of course, tacos!

Three-esta

Another fun Mexican-inspired party theme is this clever 3rd birthday spin on Fiesta: “Three-esta”! Use lots of bright colors, don a sombrero, set up a taco bar and once your guests have left, collapse for a siesta!

Three-I-E-I-O!

Invite Old MacDonald’s animals to your 3-year-old’s farm party and hear them sing “3-I-E-I-O”! Create a farm-feel with animal prints, hay balls, farm fresh food, and a big red barn!

Unique 3rd Birthday Party Themes for Girls

If you need a girl 3rd birthday party theme, look no further! Most of these great ideas are generally thought of being more “girly” (although don’t let that stop you if you think they’d fit your boy, we’re all for individual expression!), with plenty of pinks, tiaras, florals, and sparkle.

Threenager / Little Miss Threenager

They say the “terrible twos” are nothing compared to the independent “Threenager” your child turns into during their 3rd year. We beg to differ, but it does make for a very clever, tongue-in-cheek celebration that you can use to create a fun party with a spin on fashion, make-up, and #socialmedia.

Threenage Dream

Take inspiration from Katy Perry’s hit song “Teenage Dream” and create your 3-year-old’s “Threenage Dream” instead! Ask your little girl what that would look like to her – use her favorite colors, and go all-out with a fun treat like a popsicle stand or cotton candy cart!

Young, Wild and Three

We love this bohemian-inspired theme that lends itself perfectly to pretty muted colors, teepees, dream catchers, feathers and fringe!
