Salvatore John Campisi (born August 11, 1942) is an American former professional baseball player.

A right-handed pitcher, he appeared in Major League Baseball for the St. Louis Cardinals in 1969 and 1970 and the Minnesota Twins in 1971.

Campisi put up three consecutive stellar seasons at the Double-A and Triple-A levels of minor league baseball from 1967 to 1969, with a gaudy won–lost record of 36–8 (.818) in 124 games pitched, 100 of them in relief.

He worked in 50 MLB games, all as a relief pitcher, and allowed 62 hits and 47 bases on balls in 631⁄3 innings pitched.
