John Joseph Carey (February 23, 1919 - August 22, 1995), known as Johnny Carey or Jackie Carey, was an Irish professional footballer and manager. As a player, Carey spent most of his career at Manchester United, where he was the team captain from 1946 until he retired as a player in 1953.

After only two months in the League of Ireland, he was discovered by Billy Behan, a Dublin-based scout for Manchester United. Behan convinced United Chief Scout Louis Rocca to review him and in November 1936 United signed him for a record fee of £ 250 for what was then the League of Ireland. He made his debut as a left winger for United on September 23, 1937 against Southampton. During his first season at United, Carey helped United to advance to the top division along with Harry Baird, Jack Rowley, Tommy Bamford, Tommy Breen and Stan Pearson.

Carey continued to play for Manchester United during World War II, and between 1939 and 1943 he made 112 appearances and scored 47 goals in wartime regional leagues. He also played as a guest for several other clubs, including Cardiff City, Manchester City, Everton, Liverpool and Middlesbrough

After returning to Manchester United, Carey began playing as a midfielder and defender. He was also named team captain by Matt Busby. He led United as captain to victory in the FA Cup final in 1948 and to second place in the first division four times before finally winning the title in 1952. His teammates at United during this era included Jack Rowley, Charlie Mitten and John Aston. Carey played 304 league games and scored 17 goals during his career at United. In the FA Cup, he played another 38 games and scored another goal. Carey also played twice for United in the FA Charity Shield.
