Francis Anthony "Frank" Stapleton (born 10 July 1956 in Dublin) is an Irish former football player and manager. He is best remembered for his time at Arsenal, Manchester United and as a pivotal player for the Republic of Ireland. He has also been manager at Bradford City and MLS club New England Revolution.

Stapleton was a tough tackling forward who was an especially good header of the ball. He started his career with Arsenal, joining them in 1972 as an apprentice, after being turned down by Manchester United. He made his first-team debut in 1975 against Stoke City, and would go on to form a potent striking partnership with Malcolm Macdonald; the two scored 46 goals between them in 1976–77. He was Arsenal's top scorer for the three following seasons, and helped the Gunners reach a trio of FA Cup finals; Stapleton scored one of the goals in Arsenal's 1979 FA Cup Final 3–2 win over Manchester United, and scored 108 goals in 300 appearances in total for the Gunners.

Stapleton went on to move to Man United in 1981 for £900,000 (a fee set by tribunal after the two clubs could not agree). He helped United win the 1983 and 1985 FA Cups. It was in the first of those finals, when he scored against Brighton, in which Stapleton made history by becoming the first man to score for two different clubs in FA Cup Finals.^{[citation needed]} He left United in 1987, after scoring 78 goals for the club in 365 matches.
