"Suicide Is Painless" (or "Song from M*A*S*H") is a song written by Johnny Mandel (music) and Michael Altman (lyrics) for the 1970 film M*A*S*H. In addition to being performed by characters in the film, it plays during the title sequence as sung by The Ron Hicklin Singers. An instrumental version is likewise the theme music for the TV series based on the film, playing over the opening and closing credits.
