The Jinx is an American true crime documentary television series about New York real estate heir Robert Durst, a convicted murderer. The first season, subtitled The Life and Deaths of Robert Durst, debuted on HBO on February 8, 2015, and it consists of six episodes.

The series was directed by Andrew Jarecki, who had previously directed the feature fictional film All Good Things (2010), which was inspired by Durst's biography. Durst had professed admiration for the film and telephoned Jarecki after its release, offering to be interviewed (this conversation was recorded and incorporated into the documentary). Durst sat with Jarecki for more than 20 hours, over several years, despite having never previously cooperated with any journalist.

The Jinx gained widespread exposure when Durst was arrested on first-degree murder charges for the death of his friend Susan Berman the day before The Life and Deaths of Robert Durst finale aired.

In November 2023, HBO announced that The Jinx: Part Two, a six-episode continuation of the series, was in production with the same producers and director. It premiered on April 21, 2024. Part Two covers the eight years since 2015, including Durst's trial, new interviews, and prison calls.
