Let's be real: finding good mermaid films on Netflix is a lot harder than it used to be. You'd think with the massive success of The Little Mermaid remake or the cult following of shows like H2O: Just Add Water, the streaming giant would be swimming in sirens and scales. It isn't. Not exactly.
Content libraries shift like the tide. One day you've got a specific teen drama available, and the next, licensing agreements expire and it's gone. If you're searching for mermaid films on Netflix today, you’re likely encountering a mix of high-budget documentaries, a few animated features, and some "adjacent" fantasy that might not satisfy a hardcore fan of the genre.
Netflix has a weird relationship with aquatic fantasy. They tend to lean heavily into the "scary siren" trope or the "educational nature doc" angle rather than the classic romanticized mermaid. If you're expecting a dozen versions of Ariel, you’re gonna be disappointed. But if you're willing to look at how the platform categorizes "sea-dwelling humanoids," there are actually some gems hidden behind the algorithm.
Why Netflix Keeps Swapping Out Mermaid Content
Licensing is a massive headache. Most of the iconic mermaid stories belong to Disney, which means they live on Disney+, not Netflix. This leaves Netflix to either produce their own "Originals" or license international films that might only stay on the platform for eighteen months.
Take Luna Nera or Tidelands. These aren't exactly "films" in the traditional sense, but they are the primary way Netflix satisfies the itch for mermaid films on Netflix. Tidelands was their big swing at a "siren" mythos—set in a small fishing village with half-siren hybrids. It’s gritty. It’s dark. It is definitely not for kids. It also highlights a major trend: the "mermaid" is becoming a symbol of environmental dread or ancient mystery rather than a bubbly princess.
The Best Mermaid and Sea-Adjacent Titles You Can Stream
Right now, the most visually stunning thing you can watch that fits the bill is actually a documentary, but don't roll your eyes just yet. My Octopus Teacher isn't about a mermaid, but it captures the "alien world under the waves" feeling better than most CGI movies.

If you want actual tails, though, you have to look at the animated section or international releases.
Scales and Animation
Sea Beast is probably the closest high-quality thing to a mermaid movie on the platform right now, even if the "mermaids" are more like massive sea kaiju. It’s got that high-seas adventure vibe. Then there’s Barbie Mermaid Power. Look, don't judge. If you have kids—or if you just want a nostalgia hit—it’s one of the few places on Netflix where you get the classic "tail and shell" aesthetic without a side of existential horror.
The International Pivot
Netflix has been buying up a lot of Korean and Chinese content lately. This is where you find the real "mermaid" energy. While The Legend of the Blue Sea (a massive K-drama hit) bounces on and off the platform depending on your region, Netflix frequently hosts similar high-fantasy dramas that feature water deities or sea spirits. These often have higher production values than the Western B-movies you'll find in the "Related" tab.
The "Siren" Problem: When Mermaids Get Scary
There is a huge distinction in mermaid films on Netflix between "mermaid" and "siren."
Netflix loves the siren. The siren is the one that pulls sailors to their deaths. If you search for these terms, you might stumble upon horror anthologies like Love, Death & Robots. The episode "Jibaro" is a masterpiece of siren storytelling. It’s visceral, loud, and haunting. It doesn't use dialogue. It uses movement and gold-covered scales to tell a story of greed and predatory nature. Honestly, it's probably the most "expertly" crafted piece of mermaid media on the site, even if it’s only twenty minutes long.

What Most People Get Wrong About the Search
People often complain that "there aren't any mermaid movies on Netflix" because they are looking for the word "mermaid" in the title. The algorithm is smarter—and dumber—than that.
- Search for "Aquatic Fantasy": This often brings up titles that the "mermaid" keyword misses.
- Check the "International" Category: Many European films about selkies or sea folk are categorized under "International Movies" rather than "Fantasy."
- Look for "Teen Dramas": Shows like Mako Mermaids: An H2O Adventure are staples. They are technically series, but they are the backbone of the genre on the platform.
The reality is that mermaid films on Netflix are often buried under broader genres like "Sci-Fi & Fantasy" or "Kids' TV." Netflix's UI tends to show you what it thinks you want based on your history, not necessarily the most accurate list of every mermaid-themed title they own.
The Environmental Subtext in Modern Mermaid Media
If you watch Tidelands or even some of the ocean-based documentaries, you’ll notice a shift. We don't see mermaids as just "fish-people" anymore. We see them as protectors of a dying ocean. This "eco-warrior" mermaid is a relatively new trope. It replaces the "I want to have legs and marry a prince" trope with something a bit more substantial.
Experts in film theory, like Dr. Christina Flotmann-Scholz, have noted that our depiction of mermaids often reflects our current cultural anxieties. In the 80s and 90s, it was about independence and teen rebellion. In the 2020s, as seen in the selection of mermaid films on Netflix, it's about the mystery of the deep sea and the fact that we are destroying a world we barely understand.
Navigating the Netflix Algorithm for Best Results
If you want to find the "hidden" mermaid content, you need to use the secret category codes. You can type these directly into your browser if you're on a laptop. The code for Fantasy Movies is 9744, but there isn't a specific one just for mermaids. You have to combine that with "Deep Sea" searches.

Also, keep an eye on the "Coming Soon" tab. Netflix tends to drop their biggest fantasy titles in the summer or right around the holidays. They know when people want to escape into a tropical, underwater world.
Why the "Classic" Mermaid Movie is Disappearing
We are seeing a decline in the "traditional" mermaid film because CGI is expensive. Creating a realistic underwater world where hair moves naturally and tails don't look like rubber suits costs a fortune. That’s why Netflix often opts for animated versions or shows where the "mermaids" spend most of their time on land in human form (think H2O or Mako Mermaids). It’s a budget thing.
When you do find a high-budget mermaid film on Netflix, it's usually because it was a licensed acquisition from a major studio that needed a quick infusion of cash.
Actionable Steps for the Ultimate Binge
If you are ready to dive in, don't just type "mermaid" and quit.
- Broaden the search terms. Use words like "Siren," "Tide," "Sea Spirit," and "Selkie."
- Check the "More Like This" section under Mako Mermaids. Even if you don't want to watch a teen show, the "More Like This" algorithm often pulls in films that aren't tagged correctly.
- Change your profile language to Spanish or Korean. Sometimes, Netflix has licensing for mermaid content in other languages that doesn't show up as prominently on the English-language dashboard.
- Use a VPN (carefully). Licensing for mermaid films on Netflix varies wildly by country. The UK library often has different fantasy titles than the US or Canadian libraries.
The landscape of streaming is always changing. What’s there today might be gone by Tuesday. But if you know how to look past the front page, you can still find plenty of scales and salt water to satisfy your curiosity.
Start by watching the "Jibaro" episode of Love, Death & Robots for a technical masterclass, then move into The Sea Beast for a lighter adventure. If you're looking for that specific teen-drama itch, Mako Mermaids is still the gold standard for long-form storytelling in this niche.
