Birdo, known in Japan as Catherine (キャサリン, Kyasarin?), is a fictional character in the Mario series of video games, who first appeared in Yume Kōjō: Doki Doki Panic, which was localized for English audiences as Super Mario Bros. 2 and is an enemy to Mario. Since her appearance, she has been a recurring character in the series, more frequently in the Mario sports games as a playable character, as well as Mario Party titles. She has also made several cameos, particularly in the Super Smash Bros. series and the Wii video game Captain Rainbow.

Birdo's gender in the original manual for Super Mario Bros. 2 asserts that Birdo is a man who believes that he is a girl, and would rather be referred to as "Birdetta". Later releases of Super Mario Bros. 2 lacked any mention of her gender in either the game or the manual. Nintendo eventually established Birdo as female, first in Mario Tennis which depicted Birdo and Yoshi as lovers. However, several games portray her as male, such as Captain Rainbow, or refer to the gender confusion without assigning one, such as in Super Smash Bros. Brawl. It has been suggested that Birdo is a post-op transsexual by transsexual video game developer Jennifer Reitz, while Wired editor Chris Kohler felt that it was a way of retconning her transsexual status.
