The Republic of Ireland men's national football team represents the Republic of Ireland in men's international football. It is governed by the Football Association of Ireland (FAI).

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. During the same period, another Ireland team also existed; this was overseen by the Irish Football Association (IFA) and had previously been the sole national team for the entire island of Ireland. In 1953, FIFA decreed that for competitive matches in tournaments that both Irish teams could enter, the FAI team would be officially called Republic of Ireland while the IFA team was to be named Northern Ireland. Northern Ireland was allowed to keep using the title Ireland by FIFA in the British Home Championship (which was discontinued in 1984). The Republic of Ireland was the first nation from outside the United Kingdom to defeat England at home, in a fixture played at Goodison Park, Liverpool, in 1949. The team reached the quarter-final stage of the 1964 European Nations' Cup, where they lost to the eventual champions Spain.
