The McLean Stevenson Show is an American sitcom that aired on NBC on Wednesday nights from December 1, 1976, to March 23, 1977.

The series centered on Mac Ferguson, the owner of a hardware store in Evanston, Illinois (McLean Stevenson's birth state).

Mac Ferguson, a hardware store owner, was framed as a nice guy, assailed on all sides, a man caught in the middle, and a chronic victim of circumstances – similar to the character he played as Lt. Col. Henry Blake in M*A*S*H.[3] The first seven episodes were taped, with the cast and production staff expecting the series to begin airing in January 1977.

[4] As Barbara Stuart explained, while a swan song party was underway for the cast and crew, word came through that The McLean Stevenson Show had instead been spared.

It was hoped that Stevenson's popularity on M*A*S*H would draw viewers in, but the actor's first starring vehicle failed to find an audience and was cancelled after three months.
