Donna Duck is a fictional duck who is one of Walt Disney's cartoon and comic book characters. She first appeared in the cartoon "Don Donald" on January 9, 1937 as Donald Duck's girlfriend. She never reappeared in cartoons but became a regular in the Disney newspaper comic strips. She was replaced by Daisy Duck as Donald's girlfriend in 1940. Some believe that Donna and Daisy are the same character, but this can't be since both of them appeared as rivals for Donald's affection in a strip published on August 7, 1951.

Going by the information available and Disney comic writers Carl Barks's and Don Rosa's perspectives, the following has been purposed as this character's continuity: Donna was born in 1918 as an older sister of Daisy, and apparently spent a number of years in Mexico, which explains her style of dressing. She met Donald during a trip of his to Mexico in 1937. Donna became his girlfriend until around 1940 when they broke up. In the same year she married someone else and became the mother of April, May, and June Duck. She continued living in Duckburg until at least 1953. Since her daughters live with Daisy after that year, she is presumably deceased.
