Masada is an American television miniseries that aired on ABC in April 1981. Advertised by the network as an "ABC Novel for Television," it was a fictionalized account of the historical siege of the Masada citadel in Israel by legions of the Roman Empire in AD 73. The TV series' script is based on the 1971 novel The Antagonists by Ernest Gann, with a screenplay written by Joel Oliansky. The siege ended when the Roman armies entered the fortress, only to discover the mass suicide by the Jewish defenders when defeat became imminent.

The siege of Masada was one of the final events in the First Jewish–Roman War, occurring from 72 to 73 CE on and around a hilltop in present-day Israel.
