Samuel Davis (born July 4, 1944) is a retired American football player, who played for the National Football League's Pittsburgh Steelers from 1967 to 1979.
Davis played football at Allen University.
Davis was an undrafted rookie in 1967. He did not start any game during his first three years of play, but started at the left offensive guard position for the National Football League's Pittsburgh Steelers from 1970 to 1979. In 1970, Chuck Noll's second year as head coach, Davis replaced Larry Gagner and started all 14 games. From 1970 to 1979, he played next to left offensive tackle Jon Kolb and the two went on to win four Super Bowl rings together with the Steelers (Super Bowls IX, X, XIII, and XIV). However, Davis was injured during Pittsburgh's first two Super Bowls and regular reserve Jim Clack actually started in his place in Super Bowls IX and X. In 1980, he was replaced by Ray Pinney.
