Crochet dinosaur hat pattern

ByMelissa Hassler

Turn a simple crochet hat into a playful dinosaur with bold spikes, cozy earflaps, and braided ties. It’s a fun cold-weather accessory for dinosaur fans and works especially well for dress-up, costumes, photos, gifts, or everyday wear.

Quick answer

This advanced beginner crochet dinosaur hat is worked from the top down in joined rounds using worsted weight (#4) yarn. The main hat is made with an I-9 (5.5 mm) crochet hook, while the separate dinosaur spikes use a G-6 (4 mm) hook. Earflaps and braided ties are added after the main hat. The pattern includes toddler, child, and adult sizes.

Repeat for second earflap and then single crochet around the entire hat and ear-flaps with green yarn.

Adding the braids

Cut seven 30” strands of each of the blue & green yarns for a total of 14 strands per braid.

  1. Fold the strands in half and pass the folded loop through the bottom of the ear flap.
  2. Pass the strand ends through the loop and pull tight to form a knot.
  3. Divide into three sections and braid.
  4. Tie a secure knot at the end of the braid and trim the yarn ends evenly.

Dinosaur spikes pattern

Make 4 spikes using a G-6 4 mm crochet hook.

Rnd 1: Magic circle, ch 2, 6 hdc, join with sl st (6 stitches)
Rnd 2: Ch 2, *2 hdc, hdc in next 2 sts*, join (8 stitches)
Rnd 3: Ch 2, *2 hdc, hdc in next 3 sts*, join (10 stitches)
Rnd 4: Ch 2, *2 hdc, hdc in next 4 sts*, join (12 stitches)

Attach the spikes to the hat

Flatten each spike into a triangle shape. Using a yarn needle, sew the yarn tail through both sides of the spike and into the stitches of the hat to attach it securely. Repeat for each spike, spacing them evenly down the center of the hat.

Finishing the hat

Weave in all remaining yarn ends with a yarn needle and trim any excess. Your crochet dinosaur hat is now ready to wear or gift.
