Peck's Bad Girl was a 1959 American TV series, starring Wendell Corey and Patty McCormack which aired on CBS. The show revolved around the misadventures of a twelve-year-old girl growing up and how she related to her family. Patty McCormack, who had played a sinister little girl in The Bad Seed, played the lead character, Torey Peck. The title drew inspiration from the Peck's Bad Boy stories.

The show was presented as a family comedy centered on Torey, who would talk directly to the audience about herself and the events from in front of a black screen at points during the episode. Peck's Bad Girl replaced the Arthur Godfrey Show.

The New York Times said in its review of the show: "PECK'S BAD GIRL, which had its debut... is another situation-comedy series on family life and a further reminder of the sustained superiority of Father Knows Best." After its poor reception in 1959, CBS re-ran the entire series in the summer of 1960 to no better success.

Peck's Bad Girl was also the title of a 1918 silent film with an unrelated storyline.
