John Jay Martin (August 9, 1916 – March 17, 1968) was a professional football player who played in the league from 1941 to 1945. Martin played for the Chicago Cardinals, Boston Yanks and "Card-Pitt", a team that was the result of a temporary merger between the Chicago Cardinals and the Pittsburgh Steelers. The teams' merger was a result of the manning shortages experienced league-wide due to World War II. He was released from "Card-Pitt" after the team's game against the Green Bay Packers, when it was discovered that John McCarthy could average 35 yards per punt. He then signed with the Boston Yanks.
