Little Mermaid x Frozen is not an official Disney crossover film, but a popular fan-made concept that merges the worlds of The Little Mermaid (1989) and Frozen (2013). The idea gained traction because both stories are rooted in Scandinavian fairy tales, feature powerful female leads, and share thematic elements of sacrifice, love, and self-discovery. While Disney has never produced a combined movie or series, the crossover lives on through fan art, fan fiction, and fan theories—some of which speculate that the two kingdoms exist in the same universe.
Where the Crossover Idea Comes From
The crossover concept is not random. Both films are based on works by Danish author Hans Christian Andersen: The Little Mermaid is adapted from his 1837 tale of the same name, and Frozen is loosely inspired by his 1844 story The Snow Queen. Andersen was Danish, and both stories are set in or near Scandinavian-inspired settings—The Little Mermaid in an unnamed underwater kingdom and Frozen in the fictional kingdom of Arendelle, which draws heavily on Norwegian fjords and culture.
Fans have also pointed out that both films feature a royal sister or daughter who struggles with her identity and makes a life-altering choice for love. Ariel gives up her voice to be with Prince Eric; Elsa isolates herself to protect Anna. The emotional parallels make the crossover feel natural, even though the two stories have no official connection.
Are They Set in the Same Universe?
Disney has not confirmed any shared universe between The Little Mermaid and Frozen. However, a popular fan theory suggests that Arendelle and the merfolk kingdom could coexist geographically. The theory points to the fact that Frozen is set in a fictional Nordic country, and The Little Mermaid takes place in the Baltic Sea or the North Sea, both of which border Scandinavia. In Frozen 2 (2019), the story expands to include the Enchanted Forest and the spirits of earth, fire, water, and air—elements that could easily connect to a mermaid’s world.
Another clue fans cite is the presence of a shipwreck in Frozen 2 that resembles the ship from The Little Mermaid, but this has not been officially acknowledged. Disney has a history of Easter eggs, but they often serve as visual nods rather than proof of a shared canon. As of now, the two stories exist in separate continuities.
What a Crossover Would Look Like
If Disney ever produced an official crossover, it would likely be a direct-to-video or streaming special, similar to how they handled Leroy & Stitch or Once Upon a Halloween. A plausible plot might involve Ariel and Elsa teaming up to stop a villain who threatens both land and sea—perhaps Ursula’s sister or a sea spirit gone rogue.
Fans have imagined many scenarios:
- Ariel visiting Arendelle’s fjords and meeting Anna and Elsa.
- Elsa using her ice powers to create a bridge between the surface and the underwater kingdom.
- Ursula attempting to manipulate Elsa’s powers for her own gain.
- Anna and Ariel bonding over their shared love for adventurous, outgoing partners.
None of these have been produced, but they remain popular in fan communities on platforms like Tumblr, DeviantArt, and Archive of Our Own.
Fan Works and Community Response
The crossover has a robust presence in fan fiction and fan art. On Archive of Our Own, stories tagged with both The Little Mermaid and Frozen number in the thousands. Many explore the idea of Ariel and Elsa as sisters, or romantic pairings between characters from the two films—though the latter is less common because the characters are from different worlds and time periods.
Fan artists frequently depict Ariel and Elsa together, often with Elsa using her powers to create ice sculptures of mermaids, or Ariel swimming in Arendelle’s icy waters. Some fans have even created “crossover AU” (alternate universe) scenarios where Ariel is a princess of the Southern Isles, or where Elsa is a sea witch. The creativity is vast, but it all remains unofficial.
Common Misconceptions
One common misconception is that Disney has announced a crossover film. This is false. No official announcement has ever been made. Another misconception is that the two stories are connected because both are by Hans Christian Andersen—but Frozen is only loosely based on The Snow Queen, and the film’s creators have said they changed many elements. The connection is thematic, not narrative.
Some fans also believe that the character of Elsa was originally intended to be a villain, which is true—early drafts of Frozen had Elsa as a villain, but that was changed. This has nothing to do with The Little Mermaid, but the two films are often compared because both feature female protagonists who defy traditional Disney princess tropes.
Why the Crossover Appeals to Fans
The appeal lies in the shared themes of isolation, sacrifice, and the power of love. Ariel gives up her voice for a chance at love; Elsa isolates herself to protect her sister. Both are misunderstood by their families and communities. A crossover would allow these two characters to understand each other in ways that their own stories don’t permit.
Additionally, both films have iconic musical numbers and strong visual aesthetics—Ariel’s underwater world is colorful and fluid, while Elsa’s ice palace is crystalline and cold. Combining these visuals in fan art creates striking contrasts. The emotional depth of both stories, combined with their visual differences, makes the crossover a rich source of creative exploration.
Frequently Asked Questions
Is there an official Little Mermaid and Frozen crossover?
No. Disney has never produced an official crossover between The Little Mermaid and Frozen. All existing crossovers are fan-made works, such as fan fiction, fan art, and videos.
Are Ariel and Elsa related?
No. There is no canonical relationship between Ariel and Elsa. They come from different stories and different fictional worlds. Fan theories sometimes suggest they are cousins or sisters, but Disney has never confirmed any connection.
Could Elsa be a mermaid?
No. Elsa is a human queen with ice powers. In Frozen 2, she is revealed to be the fifth spirit, but she is not a mermaid. Some fan art depicts her as one, but that is purely imaginative.
What would a crossover movie be rated?
It would likely be rated G or PG, similar to both original films. Disney’s animated features are generally family-friendly, and a crossover would follow that pattern.
Where can I find fan-made crossovers?
Fan fiction can be found on Archive of Our Own (AO3), FanFiction.net, and Wattpad. Fan art is commonly posted on Tumblr, DeviantArt, and Instagram. YouTube also has fan-made trailers and music videos.
Will Disney ever make a crossover?
It is unlikely in the near future, as Disney has not shown interest in combining these two properties. However, Disney has produced crossover content for other franchises, such as Ralph Breaks the Internet (2018), which featured many Disney princesses together. So it is not impossible, but no plans have been announced.
