Mark Linden Lee (born June 14, 1953) is an American former Major League Baseball pitcher.

Lee pitched in all or part of four seasons from 1978 until 1981, the first two for the San Diego Padres and the last two for the Pittsburgh Pirates.

Lee was pitching in Triple-A for the Pirates in 1982 when he was designated for assignment.

After getting two outs in the ninth inning of a game, the second on a strikeout, Lee walked off the field while removing his jersey.

He then announced he planned to quit baseball; Lee said he wanted to strike out the last batter he ever faced.
