Orenthal James Simpson (July 9, 1947 – April 10, 2024) was an American football player, actor, and broadcaster. He played in the National Football League (NFL) for 11 seasons, primarily with the Buffalo Bills, and is regarded as one of the greatest running backs of all time. Once a popular figure with the American public, Simpson's professional success was later overshadowed by his trial and controversial acquittal for the murders of his former wife Nicole Brown and her friend Ron Goldman in 1994.

Simpson played college football for the USC Trojans, where he won the Heisman Trophy as a senior, and was selected first overall by the Bills in the 1969 NFL/AFL draft. During his nine seasons with the Bills, Simpson received five consecutive Pro Bowl and first-team All-Pro selections from 1972 to 1976. He also led the league in rushing yards four times, in rushing touchdowns twice, and in points scored in 1975. In 1973, he became the first NFL player to rush for more than 2,000 yards in a season, earning him NFL Most Valuable Player (MVP), and is the only NFL player to do so in a 14-game regular season. Simpson holds the record for the single-season yards-per-game average at 143.1. After retiring with the San Francisco 49ers in 1979, Simpson pursued an acting and broadcasting career. He was inducted into the College Football Hall of Fame in 1983 and the Pro Football Hall of Fame in 1985.
