Third Birthday Invitation Ideas for a Preschooler's Party

Three is a fun age to design around

By age three, kids usually have clear preferences — a favorite color, a favorite animal, a favorite anything — which makes the third birthday one of the easier ones to theme, since you're often building around something your child already loves rather than guessing.

Third birthday invitation styles to consider

Boho floral, "Young, Wild, and Three"

The "Young, Wild, and Three" invitation uses the number three as wordplay, with a boho pastel floral look that works well for an outdoor or garden-style third birthday party.

Race car, for a speed-loving three-year-old

If your three-year-old is all about cars and motion, the "Can't Catch Me, I'm Three" race car invitation leans into that energy with a bold, red racing design.

Dinosaur, for a classic third-birthday theme

Dinosaurs remain one of the most requested third birthday themes — see our full dinosaur birthday invitation guide for age-specific designs, including a "Three-Rex" template built specifically for this age.

What to include on a third birthday invitation

• The child's name, age, and (if using a themed pun like "Three-Rex" or "Young, Wild, and Three") make sure the wording still reads clearly to adult guests
• Date, time, and location, with any notes about outdoor vs. indoor setup
• RSVP details, since three-year-old guest counts often affect activity planning (a bounce house, a craft table, etc.)
• Any dietary or allergy notes, since preschool-age guests often have specific needs

Frequently asked questions

How do I pick a theme if my three-year-old likes several things?

Pick the one they're currently most excited about — interests at this age shift quickly, so leaning into whatever has their attention right now tends to work better than trying to combine several themes into one invitation.

Are pun-based invitations (like "Three-Rex") confusing for guests?

Not usually — as long as the date, time, and location are still clearly listed, a playful title doesn't interfere with the practical details.

What if I want a girl-specific third birthday theme?

The boho floral "Young, Wild, and Three" design above works well for a girl's third birthday, or see our Girls & Pretty collection for more options.
