The Republic of Ireland national football team (Irish: Foireann peile náisiúnta Phoblacht na hÉireann) represents Ireland in association football. It is governed by the Football Association of Ireland (FAI) and plays its home fixtures at the Aviva Stadium in Dublin.

The team made their debut at the 1924 Summer Olympics, reaching the quarter-finals. Between 1924 and 1936, the team competed as the Irish Free State and from then until 1950, it was referred to by the FAI as Éire or Ireland. In 1953, FIFAdecreed that for competitive matches in tournaments that both Irish teams may enter, the FAI team would be officially called the Republic of Ireland while the IFA team was to be named Northern Ireland.^[2] Northern Ireland was allowed to use the title Ireland by FIFA in the Home International Competition until it was discontinued in 1984. The Republic of Ireland was the first nation from outside the United Kingdom to defeat England at home at a fixture played at Goodison Park, Liverpool, in 1949. The team also reached the quarter-final stage of the 1964 European Nations' Cup, where they lost to the eventual winners Spain.
