Kathryn McGuire (1903-1978) was an American actress primarily known for her career in silent films. She began as one of Mack Sennett's celebrated "Bathing Beauties," but her fame grew exponentially thanks to her leading female roles alongside Buster Keaton.

She is particularly remembered for her performances in Keaton's comedy masterpieces such as *The Navigator* (1924) and *Sherlock Jr.* (1924), where she often portrayed the ingenue, the girl-next-door, or the protagonist's love interest. McGuire was admired for her beauty, natural grace, and the vivacity she brought to her characters, making her a beloved presence on the silent screen. Her career slowed down with the advent of sound film, leading her to retire from the screen in the early 1930s.
