35 Sims 4 Mermaid CC for a Magical Underwater Adventure
Are your mermaid Sims feeling more fish than fabulous?
Dive into this post for the best Sims 4 mermaid CC to transform your underwater sims into the true queens and kings of the sea! ๐
Island Living is one of my favorite packs (and honestly, I think one of the most essential ones)!
Besides a whole new world, we have got even a new mythical creature with merfolk! That alone could have been its own game, right?
But, of course, there’s only so much an expansion pack can include, and items from the EP alone just aren’t enough. That’s why I put together this list to share some of my favorite mermaid CC pieces.
Here, you’ll find everything you need for the perfect mermaid look! We are talking tails, skins, makeup, furniture, clothes, etc. I’ve gathered different styles of mermaid stuff so you can pick what you love the most.
I try not to repeat the same Sims 4 CC in my roundups, so I didn’t want to include every Sims 4 mermaid CC I love here since they’re already in other posts. But they’re amazing and definitely worth checking out, so take a look at those, too:
- 35 Gorgeous Sims 4 Tattoo CC for Unique Skin Stories (gorgeous mermaid gills tattoo)
- 41+ Most-Wanted Sims 4 Fantasy CC (Maxis Match & Updated) (merman and mermaid tails, poses, skin overlays)
- 35 Best Sims 4 Couple Poses for That Extra Spark (human-mermaid couple pose pack)
- 49+ Best Sims 4 Trait Mods for All Your Sims’ Unique Quirks (occult fanatic trait)
- 33+ Best Sims 4 Makeup CC Finds to Elevate Your Glam Game (sirens makeup)
- 47+ Must-Have Sims 4 Eyelashes CC for Madly Stunning Sims (mermaid eyelashes)
This post is all about the best Sims 4 mermaid cc finds.
1. Expanded Sims 4 Mermaids Mod by SpinningPlumbobs
I know this is a mod and not a simple CC you are probably looking for, but I HAVE to mention it first before we have moved on.
If you love playing with mermaids and don’t have this mod yet, you’re seriously missing out! That’s where you start!
Check out the trailer above to see all the amazing stuff you get with this modโnew objects, items, skills, perks, weaknesses, interactions, and even children mermaids. Just head to SpinningPlumbob’s Patreon download page and see for yourself!
The best part? Unlike an EP, this mod is completely free! Honestly, I think these features should’ve been in the Island Living expansion from the very beginning.

12. Mermaid Ears by Suzue

We’ve already seen these mermaid ears for infants, and now here’s the adult version from Suzue for both males and females.
I love these ears for their unique look. They’re perfect if you want to create occult Sims that look less human.
13. Siren Core CC collection by Belaloallure

I know this clothing collection isn’t strictly mermaid CC, but the inspiration for this set came from The Little Mermaid, so I think it’s still valid to get a place on the list!
And it’s gorgeousโjust look at the seashell top! It’s very much mermaid-style, isn’t it? This set would be the perfect clothing option for when your Sims are in their human sim form.
14. Aurelia Sims 4 Mermaid CC Top by Beto-AE0

Check out this Sims 4 mermaid cc top by Beto! It’s decorated with pearls and made of seashells, giving it a classic mermaid look.

21. Gun Show Fangs by Pyxis

Sometimes, I want to create a dangerous creature, and these fangs are a must! They add instant creepiness and make any occult Sim look more dangerous.
I know, they’re usually used for aliens or vampires, but I think mermaids should be pretty scary, too!

24. Lunae Sims 4 Mermaid CC Set by DanSimsFantasy

This set includes a top and tail for mermaids, and though it sounds usual, the design is so unique! That’s what I love this CC pack for.
There are over 40 color swatches for each item, and they look kind of like opalโslightly transparent and shimmery, reminding me of jellyfish. The top is gorgeous, showing fish skin on one breast and fabric covering the other.
The glove (or sleeve) part looks like algae growing on your Simโsuper cool!
25. Yura Shell Top by Belaloallure

This seashell crop top is perfect for your mermaids when they go on land or decide to turn into humans. It keeps the vibe and stays true to their Sim style.

This CC works for both genders and all occult Sims except werewolves.
29. Song of the Deep Sea by Mayasims

As you can see, it’s not specific to mermaids, but you can definitely use it to get creative with them!
35. Siren Ears by TekriSims

Here’s another cc set with beautiful siren earsโbig fish ears with membranes. They’re unisex, and you can choose whether you want them pierced or not.
