Minnie Mouse is probably best known for being Mickey Mouse’s girlfriend or wife, but there’s a lot more to this little mouse than meets the eye. This polka-dotted icon made her debut in the animated film Steamboat Willie in 1928 alongside Mickey, who also made his first onscreen appearance in the film. Since then, she’s been an iconic and beloved member of the Disney gang. Here are eight fun facts about Minnie Mouse.
- Minnie Mouse has dated mice other than Mickey
- Minnie has never starred in her own Disney theatrical release
- Walt Disney originally voiced Minnie
- Minnie has two nieces
- Pluto made his first appearance as Minnie’s pet
- Minnie’s full first name isn’t Minnie
- Walt Disney has confirmed Minnie and Mickey’s relationship status…kind of
- Minnie Mouse is a fashion icon
Minnie Mouse has dated mice other than Mickey
In a 1936 short called Mickey’s Rival, viewers are introduced to Minnie’s former love, Mortimer Mouse, while Minnie and Mickey are on a picnic date. Mortimer’s interruption causes a great deal of distress for Mickey, who makes fun of Minnie for praising Mortimer. “You’re just jealous!” she teases, and of course, chaos ensues.
Minnie has never starred in her own Disney theatrical release

Mickey Mouse has certainly been the subject of countless Disney features, but Minnie has never starred in a major full-length theatrical release of her own. She has starred in many of her own shorts, though, sometimes without Mickey, and has also headlined television specials.
Walt Disney originally voiced Minnie
Disney himself provided the original voice for Minnie and Mickey Mouse in Steamboat Willie, which aired in November 18, 1928. Later that same year, though, Disney passed Minnie’s voice on to an 18-year-old artist named Marcellite Garner, who made her debut as Minnie in the 1929 short film The Barn Dance.
Minnie has two nieces
Mickey famously has twin nephews named Morty and Ferdie, but Minnie also has two twin nieces named Melody and Millicent who first appeared in 1962. The kids are often seen playing together.
Pluto made his first appearance as Minnie’s pet

Minnie has had a number of pets over the years, including a black tuxedo cat named Figaro and a dog named Fifi. In the 1930 short The Picnic, though, she was shown with a pet dog who might look quite familiar to viewers. This was Pluto, and the appearance marked the second time viewers encountered him onscreen (he had also appeared earlier that year in the short film The Chain Gang). Though he is named Rover in The Picnic, he was soon reintroduced as the Pluto fans know and love.
Minnie’s full first name isn’t Minnie
A 1942 comic strip entitled “The Gleam” revealed that Minnie’s full name is actually Minerva Mouse. According to Walt Disney himself, the name was a tribute to Minnie Cowles, who was the wife of Dr. John Cowles—an investor in one of Disney’s earliest film studios, Laugh-O-Gram Studios.
Walt Disney has confirmed Minnie and Mickey’s relationship status…kind of
In some features, Mickey is seen pursuing Minnie and trying to win her over, but ultimately, according to Disney itself, the pair are very much in it for the long haul. “In private life, Mickey is married to Minnie… What it really amounts to is that Minnie is, for screen purposes, his leading lady,” Disney told Film Pictorial magazine in 1933. Still, Disney later told The News Chronicle that the pair really aren’t technically married, as divorce truly isn’t an option for them. “There’s no marriage in the land of make-believe,” he said. “Mickey and Minnie must live happily ever after.”
Minnie Mouse is a fashion icon

Minnie's famous polka-dotted outfits have had a significant impact on fashion over the years, so much so that an exhibition called Minnie: Style Icon opened in London in 2015. Her style has been emulated by everyone from Madonna to Twiggy, and Stella McCartney even designed a pantsuit for Minnie to wear at Disneyland Paris.
