Oliver David Thompson, Esq. (September 24, 1855 - June 10, 1925) was an early football player at Yale, who played alongside Walter Camp.
 After his time at Yale, Thompson played, and served as the manager, for the Allegheny Athletic Association.
 However Thompson is best known for paying Pudge Heffelfinger $500 to play for Allegheny against their rivals, the Pittsburgh Athletic Club.
 Thompson's historic actions went unnoticed until the 1960s, when an 1892 account ledger prepared by Thompson – while he was manager of the Allegheny Athletic Association – included the line: "Game performance bonus to W. Heffelfinger for playing (cash) $500."
 The ledger is currently on display at the Pro Football Hall of Fame in Canton, Ohio.
