Otis Floyd Lamson (September 13, 1876 – December 11, 1956) was an American football player and coach, and also a surgeon.

[2] Lamson served as the head football coach at the University of North Carolina at Chapel Hill in 1907.

Prior to his coaching career, Lamson played college football while attending the University of Pennsylvania.

During that two-game series, a betting scandal involving the Tigers and their rivals, the Canton Bulldogs, arose.

Lamson graduated from the University of Pennsylvania Medical School in 1907, after which he practiced medicine in Seattle for 41 years, until his retirement in 1952.
