That Girl is an American television sitcom that ran on ABC from September 8, 1966, to March 19, 1971. It starred Marlo Thomas as the title character, Ann Marie, an aspiring (but only sporadically employed) actress who moves from her hometown of Brewster, New York, to try to make it big in New York City. Ann has to take a number of offbeat temp jobs to support herself in between her various auditions and bit parts.

It was one of the first sitcoms to focus on an unmarried woman who was not a domestic or living with her parents, a forerunner of The Mary Tyler Moore Show.

Ted Bessell played her boyfriend Donald Hollinger, a writer for Newsview Magazine. Lew Parker and Rosemary DeCamp played Lew Marie and Helen Marie, her concerned parents. Bernie Kopell and Ruth Buzzi played Ann and Donald's friends. That Girl was developed by writers Bill Persky and Sam Denoff, who had served as head writers on The Dick Van Dyke Show (which Thomas' father, Danny Thomas, co-produced) earlier in the 1960s.
