The Legend of Lizzie Borden is a 1975 American historical mystery television film directed by Paul Wendkos and starring Elizabeth Montgomery—in an Emmy-nominated performance—as Lizzie Borden, an American woman who was accused of murdering her father and stepmother in 1892. It co-stars Katherine Helmond, Fritz Weaver, Fionnula Flanagan, and Hayden Rorke. It premiered on ABC on February 10, 1975. The film was nominated for a Golden Globe award for Best Motion Picture Made for Television in 1976.

Although the film is based on fact, it is a stylized retelling of the events of August 4, 1892, the day the father and step-mother of New England spinster Lizzie Borden were found brutally murdered in their Fall River, Massachusetts home. Public interest in Borden and the murders is exacerbated by her aloof demeanor after the murders, and the public speculates about her involvement in them when she fails to express any emotion during her father and stepmother's funerals.

The subsequent incarceration of the prime suspect (Lizzie herself) as well as the coroner's inquest and the trial are faithfully depicted, using actual testimony. During the trial, various persons testify, including Bridget Sullivan, the Borden's maid from Ireland who was the only other person in the home at the time of the murders.

In what may be seen as a deviation from the film's docudrama narrative, as Lizzie hears her verdict, flashbacks are shown of her actually committing the murders in the nude and bathing after each death, explaining why no blood was ever found on her or her clothes; however, the film's plot with regard to Lizzie's role in the murders remains ambiguous because it does not state that Lizzie was actually reminiscing about the crimes nor does it state that she was simply fantasizing about how she herself would have disposed of her victims. When Lizzie returns home after her acquittal, her sister Emma asks her point-blank if she killed their father; Lizzie does not answer. The epilogue states that the killings of Andrew and Abby Borden remain unsolved.
