Orin Kirkpatrick Pressley[1] (June 24, 1907 – September 22, 1984) was an American college football player and coach and a lieutenant colonel in the United States Marine Corps.

[3] Pressley was the school's first All-American,[4][5][6][7] when he received third-team honors from Walter Trumbull, John Heisman, and the Newspaper Enterprise Association.

"[11] Clemson wore orange jerseys for the first time in 1928, and Pressley starred in the rivalry game with South Carolina, recording four tackles for a loss in a row despite a hand injury.

Pressley of Clemson is hard to find,” remarked former South Carolina head coach Billy Laval.

The team is composed of selected players from the entire Marine Corps, and is considered one of the best service elevens in the country.
