"Goodbye, Farewell, and Amen" is a television movie that served as the 251st and final episode of the M*A*S*H television series. Closing out the series' eleventh season, the 2½-hour episode first aired on Monday, February 28, 1983. Written by a large number of collaborators (including series star Alan Alda), and directed by Alda, "Goodbye, Farewell, and Amen," as of 2008, is still the single most watched episode of a television series in American history.

The episode's plot chronicles the waning days of the Korean War at the 4077th MASH and features several storylines intended to show the war's effects on the individual personnel of the unit, and to bring closure to the series. After the final cease-fire of the war goes into effect, the members of the 4077th threw a closing party before going about the process of dismantling the camp for the final time. After saying their tear-filled goodbyes, the main characters go their separate ways, leading up to the iconic final scene of the series. The episode drew 106 million Americans, more than both that year's Super Bowl and the famed Roots miniseries. The episode remains one of the most respected of the series. While the M*A*S*H series ended with this episode, three of the series' main characters (Sherman Potter, Maxwell Klinger, and Father Mulcahy) would later meet again in 1983 - 1985 spin-off series AfterMASH.
