List of NFL annual interceptions leaders
In American football, an interception (INT), also known as a pick, occurs when a pass intended for a player of the same team is caught by an opposition player, who then gains possession for their team. The National Football League (NFL) did not begin keeping official records until the 1932 season and did not begin tracking interceptions until 1940.
