The Leftovers is an American supernatural drama television series created by Damon Lindelof and Tom Perrotta that aired on HBO from June 29, 2014, to June 4, 2017. Based on Perrotta's 2011 novel, the series begins three years after the "Sudden Departure", a global event that resulted in 2% of the world's population disappearing. The lives of police chief Kevin Garvey (Justin Theroux) and his family, along with grieving widow Nora Durst (Carrie Coon) and her brother, Reverend Matt Jamison (Christopher Eccleston), are the focal points of the series as they struggle to adjust to life after the Departure.

The pilot was written by Lindelof and Perrotta and directed by Peter Berg. The series stars an ensemble cast led by Theroux and features Amy Brenneman, Christopher Eccleston, Liv Tyler, Chris Zylka, Margaret Qualley, Carrie Coon, Ann Dowd, Regina King, Jovan Adepo, Kevin Carroll, Janel Moloney, and Scott Glenn. The series was renewed for a second season, which premiered on October 4, 2015, and concluded December 6, 2015. On December 10, 2015, at Lindelof's request to be able to conclude the series, HBO renewed it for a third and final season, which premiered on April 16, 2017, and concluded on June 4, 2017. Over the course of the series, 28 episodes aired over three seasons.

The first season received mostly positive reviews, though some criticized the series for its grim tone. The series underwent a critical reevaluation during its acclaimed second and third seasons, with many critics referring to The Leftovers as one of the greatest television series of all time, with particular praise for its writing, directing, acting (particularly Theroux's and Coon's) and thematic depth. The musical score composed by Max Richter also attracted critical praise. Despite receiving average Nielsen ratings throughout its run, the series has developed a cult following. The series has been compared favorably to Lost, a previous series co-created by Lindelof.
