Mike Karr is a fictional character in the long-running daytime soap opera The Edge of Night.

Karr was played by three actors: John Larkin (radio's Perry Mason)[1] from the show's debut in April 1956 to October 1961, Laurence Hugo from November 1961 to June 1, 1971, then Forrest Compton from June 2, 1971 until the show ended on December 28, 1984.

Mike and Sara Lane (Teal Ames) were dating at the beginning of the series and had enormous chemistry together.

After a respectable period of mourning for his late wife Sara, Mike began dating reporter Nancy Pollock (Ann Flood).

The couple enjoyed one of the most stable marriages in soap opera history despite the constant threat of murder and mayhem (much of it introduced due to Mike's involvement with the Crime Commission).
