Clive Harold Rush (February 14, 1931 – August 22, 1980) was an American football player and coach at both the professional and collegiate levels.

Rush then became an assistant with the New York Jets of the American Football League in 1963, serving as the main architect of the team's high-powered offense that was later led by Joe Namath.

As offensive coordinator, he reached the high point of his career when he mapped the Jets' game plan as they upset the heavily favored Baltimore Colts in Super Bowl III on January 12, 1969.

One bizarre indication of Rush's luck came on February 12, 1969, when he introduced the team's new general manager, George Sauer, Sr.

During Boston's sixth straight loss of the 1970 season, a 45–10 defeat to the Buffalo Bills on the first of November, Rush began to suffer an irregular heartbeat and briefly left the stadium.
