Keith Lincoln (born May 8, 1939) was an all-around player and the school's career rushing leader. He maintained his versatility after being drafted by the American Football League's San Diego Chargers in 1961. In 1963 he led the team in rushing, punt return and kickoff return yards. In the 1964 American Football League Championship game, he accounted for 349 yards of total offense as the Chargers defeated the Boston Patriots 51-10. A five-time All-American Football League selection (1962, 1963, 1964, 1965 and 1967), Lincoln produced unforgettable plays virtually every season. In 1961 he caught a record-setting 91 yard TD pass; in 1962, he ran a kickoff back for a Chargers' record 103 yards. Lincoln had three games in which he gained 100 or more yards on 14 or fewer carries, and in both 1963 and 1964 was the AFL All-Star Game Most Valuable Player.
Lincoln is a member of the San Diego Chargers and Washington State University Athletic Halls of Fame.
In 1995, a panel of experts commissioned by The Spokesman-Review to commemmorate the 100th anniversary of football at Washington State University named Lincoln to the school's all-time team. A similar honored was bestowed on him in 1998 when Cougfan.com named him to its all-time Cougar team.
After retiring from pro football, Lincoln returned to WSU as an assistant coach and then became the school's long-time director of alumni relations.
