The New Leave It to Beaver is an American sitcom sequel to the 1950s and '60s series, Leave It to Beaver. The New Leave It to Beaver began with the 1983 CBS TV movie Still the Beaver, and was picked up in 1984 as a Disney Channel series with the same name; however, it only lasted one season. It was then picked up by TBS in 1986 and renamed The New Leave It to Beaver. The series, also syndicated in the late 1980s, lasted until June 1989.

It is one of the rare examples of a television series revival sequel that revolves around the characters from the original series. Other examples of this would be The New WKRP in Cincinnati, The Brady Brides, What's Happening Now!! and the 2012 version of Dallas. The New Leave It to Beaver is the second longest running of any series revival in television history.
