11+ *Coolest* Baby Boy Halloween Costumes for 2025

Halloween is truly one of my favorite times of the year! It’s the perfect time to let your creativity come alive through costumes and decorations.

If you’re a parent who’s searching for the perfect Halloween costume for your baby boy, you (fortunately) have endless adorable possibilities ahead of you!

From classic characters to modern favorites, there’s a costume for every baby boy that’s sure to make this holiday fun and memorable. Let’s dive into some charming and creative costume ideas that will have your baby boy stealing the Halloween spotlight in 2025!

First on my list of baby boy Halloween costumes is the ever-popular Baby Yoda!

Baby Yoda (actually named Grogu) has captured hearts worldwide, and this beloved character is perfect for introducing your little one to the world of Star Wars.

While you can order a Baby Yoda outfit online from any major retailer, I personally love the look of this crocheted costume!

If you’re looking for something a little on the eerie side, a Halloween bat costume might be just what you need.

This costume is simple yet effective, and it can easily transition from a day at the pumpkin patch to an evening of trick-or-treating. Go for a colorful ensemble to add a bright, festive feel to all the Halloween memories you’re sure to capture!

A cute Pikachu costume is perfect for bringing an electric charm and a pop of color to Halloween night in 2025! Add pointy felt ears and a lightning-shaped tail to a simple yellow onesie to transform your baby boy into this Pokémon.

If your baby boy is ready to rock, why not dress him as his (or your) favorite pop star?

This costume idea allows you to get creative and really customize the aesthetic, as you can dress your son as a modern star, such as Bruno Mars, or a musical icon, like Elton John.

For something silly and playful, consider a strongman costume (extra points if this costume is for your newborn baby boy!)

Take inspiration from those classic, vintage circus looks and use a fake mustache, a padded barbell, and a striped leotard. It’s guaranteed to draw laughs and compliments!

Speaking of the vintage circus aesthetic, a traditional clown outfit is a cute and classic choice for Halloween.

Opt for a simple look with a neutral outfit. Or use bright colors, oversized shoes, and a tiny red nose to make this costume stand out.

For the Mama who adores fairy tales and folklore, a garden gnome costume is a perfectly charming choice. Your baby boy can don a pointy hat, a fluffy beard, and a little vest to transform into the cutest gnome in the garden.

This costume is perfect for capturing those magical, whimsical photos that will be treasured for years to come!

A Pillsbury doughboy costume is iconic, and I love this plush, playful idea for a baby boy in Halloween 2025. Finish the ensemble with a Pillsbury chef hat, and hand your little one a silicone spatula, whisk, or spoon for the cherry on top.

For a roaring good time, a lively lion costume is a fantastic pick. A warm brown onesie with a soft mane and fluffy tail is perfect for transforming your baby boy into the king of the Halloween jungle.

Your courageous boy will be soft and snug while trick-or-treating and is sure to draw at least a couple of awws throughout the night!

A colorful crayon costume adds a creative twist to the Halloween mix.

DIY this costume with a vibrant onesie, black felt, and a headband to create a unique and artistic look this Halloween. I love the orange onesie as a base for a classic Halloween look, but purple and green are excellent alternatives that still offer a festive feel.

Inspired by a bowl of delicious ramen, this adorable Cup O’Noodles costume offers a unique and fun aesthetic for Halloween.

Use a cute noodles shirt or onesie and literally top the look off with yellow, noodle-like yarn and a sprinkle of diced veggies! Your baby boy will be the cutest dish around with this playful nod to everyone’s favorite comfort food.

This adorable shark costume is bound to make waves this Halloween! A plush shark suit with super sharp teeth is perfect for a simple yet scary costume for this holiday.

Go for a classic grey shark onesie, or add a splash of color with an ocean blue version instead!

Whether you choose a wise Baby Yoda outfit or a cute clown costume, one of these baby boy Halloween costumes will make this holiday unforgettable!
