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. In addition to the NFL interception leaders, league record books recognize the interception leaders of the American Football League (AFL), which operated from 1960 to 1969 before being absorbed into the NFL in 1970. The NFL also recognizes the statistics of the All-America Football Conference, which operated from 1946 to 1949 before three of its teams were merged into the NFL, since 2025.
