What was the name originally proposed for Mickey Mouse?

The name originally proposed for Mickey Mouse was Mortimer Mouse.

Quick Scoop

• Original proposed name: Mortimer Mouse
• Final name: Mickey Mouse
• Who suggested the change: Lillian Disney, Walt Disney’s wife
• Reason for the change: “Mortimer” was felt to sound too serious/pompous for a cheerful cartoon mouse.

The Story Behind the Name Change

When Walt Disney and Ub Iwerks were creating a new character after losing Oswald the Lucky Rabbit , they decided on a mouse as their new mascot. In early planning, Walt referred to the character as Mortimer Mouse.

According to multiple accounts, when Walt mentioned this name to his wife Lillian, she immediately objected. She thought “Mortimer” sounded too formal and pompous for the kind of playful, friendly character they wanted to create. Lillian suggested “Mickey” instead, which Walt liked and which she approved with a nod.

That one-word suggestion—“Mickey”—became the name of one of the most famous characters in global entertainment history.

A Small Twist on the “Mortimer” Myth

There is also a more nuanced story: Walt had once had a real tame mouse in his early Kansas City studio that he named Mortimer, and that mouse partly inspired the idea of a mouse cartoon character. But even then, he decided to call the cartoon character Mickey , not Mortimer, and his wife’s reaction to “Mortimer Mouse” as a cartoon name was just a quick “no” rather than a long debate.

So while “Mortimer” was definitely floated as the original cartoon name, it never went beyond a brief suggestion before being replaced by Mickey. Information gathered from public forums or data available on the internet and portrayed here.
