Amigurumi Seahorse Crochet Pattern

by | All Designs, Crochet, Free Patterns, Kids & Toys, My Favorites, Summer

I’m a little behind on the Amigurumi Advent Calendar Crochet-Along due to a bad cold, so let’s just get right to the pattern for today, an amigurumi seahorse!

Crochet an Amigurumi Seahorse

Honestly, this was one of the last amigurumi that I designed for the advent calendar because I thought it’d be too difficult to get the right shape while keeping it small, and have too many pieces to sew on. It just nagged at me, but I realized this was something I really wanted to make and I should just buckle down and think it through. In the ends, I’m super pleased with how it turned out, and it’s simpler than you’d expect!

The seahorse is worked in continuous rounds, from the tail all the way up to the head, so it’s no different than the pomegranate or the persimmon in that respect. It’s just that shaping that’s different. And here’s the secret: there’s a piece of pipe cleaner in the tail to create that telltale seahorse curl. Other than the pipecleaner stuck into the tail, the construction of the seahorse is pretty straight-forward. Once the body is finished, you’ll sew on the nose, the back mane, and the side fins, all of which are easy to do.

I can’t wait to see what jewel colors everyone makes their seahorse!

You can also purchase an inexpensive PDF of this crochet pattern from my pattern shops! The PDF is formatted for easy printing and downloading and includes the instructions and photos you see here.

  • st(s) – stitch(es)

  • sk – skip
  • ch – chain stitch
  • sc – single crochet
  • inc – increase: work 2 sc in same st
  • dec – decrease: work 2 sc together
  • FLO – front loop only

Pattern Notes

  • Rounds in the seahorse are worked continuously with no seams.
  • Mane is worked in rows and then sewn on to the back of the seahorse.
  • First few rounds are worked into front loops only to make it easier on those tight rounds. Make sure to not crochet too tightly. You’ll need to fit in a pipe cleaner!
  • Pipe cleaner should have both ends turned in so there’s no sharp edges. Final length of pipe cleaner is about 2″.
  • Eyes are placed approximately 1.0-1.25 inches apart.
  • Amigurumi can be closed using this technique.

    I have been enjoying this so much!!! I hope you get to feeling better soon. This is my favorite so far!!!

    I have been posting pictures of my completed amigurumi on my Facebook page, but I’m not so great with the #’s and @’s. I have been including the #AmigurumiAdventCAL and @1dogwoof in every post. Hope that somehow makes it back to you!

    Oops I’m thinking this should say insert pipe cleaner after round 4? “After Round 6, insert pipe cleaner into the tail. Continue working Rounds 4-6 around the pipe cleaner.”
    I hope your cold goes away and you feel better soon.

    I’ve been making your jellyfish for friends having babies and they’re a huge hit. I’ve miniaturized them for a sea-themed portable playmat and this little guy makes a perfect pal for the jellyfish! Loving your patterns. Thanks for posting.

    Thank you so much for this adorable pattern. My 10 year old daughter saw this pattern and wanted to make one of these gorgeous little seahorses, and it turned out perfect. She now wants to make five more of them in all the colours of the rainbow. Thank you so much.

    I crochet the beautiful seahorse for my grandchildren to the passed "seahorse”; while swimming. It’s a very good guide, THANK YOU.
