John “Jack” Beckett (January 5, 1892 – July 26, 1981) was an American football offensive tackle who played for the University of Oregon and Mare Island. Born in rural northeastern Oregon, Beckett attended Eugene High School in Eugene before enrolling at the University of Oregon.

University of Oregon
Although primarily used as an offensive tackle, Beckett excelled at several positions, occasionally playing halfback and punter. Beckett was the team captain in his senior year of 1916 and was named to the all-Pacific Coast Conference team. He led the team to an undefeated record and tie for the conference championship with the University of Washington. Oregon was chosen to represent the conference in the 1917 Rose Bowl where they defeated Pennsylvania 14-0, with Beckett named the game’s most valuable player.

U.S. Marine Corps service
With the United States’ entry in World War I, Beckett joined the Marines in his senior year, and was assigned to the Marine base at Mare Island, California. He joined the Mare Island football team, coached by Beckett’s Oregon coach Hugo Bezdek, and was selected as team captain. With the U.S. at war, the 1918 Rose Bowl featured two service teams: Beckett’s Mare Island team and the U.S. Army’s Camp Lewis team, with Mare Island winning 19-7. Beckett is the only person to have been the captain of two different Rose Bowl teams.

Beckett served 50 years in the Marines, coaching Marine teams at Mare Island, Quantico, and San Diego, amassing an overall coaching record of 56-19-3. He achieved a final the rank of brigadier general.

Beckett was named to the College Football Hall of Fame in 1972, and was a charter member of both the University of Oregon Athletic Hall of Fame in 1992, and the Oregon Sports Hall of Fame in 1980. He died in La Jolla, California in 1981.
