Daisy Duck is one of Walt Disney's cartoon and comic book characters. She was created as a female counterpart and girlfriend to Donald Duck, and first appeared in the cartoon Mr. Duck Steps Out on June 7, 1940.

Daisy has Donald's temper but is much more in control about it, and tends to be more sophisticated than her boyfriend.

According to the various comics written by Carl Barks and Don Rosa, Daisy was "born" in 1920. She may or may not be a descendant of Pintail Duck. According to Rosa, Daisy is the sister of Donald's brother-in-law — Daisy's brother had married Donald's twin sister, Della Thelma Duck, and together, the two became the parents of Huey Duck, Dewey Duck, and Louie Duck.

Daisy replaced an earlier, short-lived character named Donna Duck, who's now treated as Daisy's older sister. Donna is the mother of triplets April, May, and June Duck, who serve as Huey, Dewey, and Louie's female counterparts.

Occasionally Daisy also dates Donald's cousin, Gladstone Gander.

In the Kingdom Hearts series, she cameod as a countess in Disney Castle with her relations to Donald intact.

Daisy will co-star in the children's television series Disney's Mickey Mouse Clubhouse.
