Saturday Night's Main Event is a professional wrestling television program that was produced by the World Wrestling Federation (now known as WWE). Premiering in 1985, it originally aired on NBC as 29 occasional replacements for Saturday Night Live until 1991, then twice on Fox in 1992. It was revived in 2006 for five NBC episodes before ending in 2008.

At the time of the original airing, it was a rare example of professional wrestling being broadcast on an over-the-air commercial television network after the 1950s. It coincided with and contributed to the apogee of the "second golden age" of professional wrestling in the United States. In a time when weekly programming consisted primarily of established stars dominating enhancement talent, Saturday Night's Main Event was made up almost entirely of star vs. star bouts, including title matches and specialty matches such as steel cage matches, handicap matches, etc.

All episodes of Saturday Night's Main Event are available for streaming on the WWE Network, some slightly altered. May 1985–January 1988 episodes do not have the original opening and closing theme songs. Sponsored segments that aired as part of the original broadcasts such as the "Mountain Dew Slam of the Night" have been removed as well.
