Patrick Andrew Haggerty (June 30, 1927 – December 9, 1994) was an American football official in the National Football League (NFL) from 1965 to 1992. In his 28 seasons in the NFL, he was selected as the referee in three Super Bowls, XIII in 1979, XVI in 1982, and XIX in 1985. He wore the number 40 for most of his career (was number 4 from the 1979 to 1981 NFL seasons when the numbering system for officials was temporarily modified). Haggerty's trademark signal upon a team scoring a touchdown, field goal or extra point, featured raising both arms, but momentarily pausing them before raising them over his head.
