The League of Ireland Men's Premier Division, also known as the SSE Airtricity Men's Premier Division for sponsorship reasons, is a professional association football league in the Republic of Ireland and the highest level of the Republic of Ireland football league system. Contested by ten clubs, the league operates on a system of promotion and relegation with the League of Ireland First Division.
The division was formed in 1985 following a reorganisation of the League of Ireland. St Patrick's Athletic and Bohemians are the only current League of Ireland clubs never to have been relegated from the Premier Division. The league has been won on two occasions by Northern Ireland-based club Derry City, the presence of which within the league makes it a cross-border competition. Since 2003, the Premier Division has taken place from spring to autumn. The 2025 League of Ireland Premier Division became the first year that the league is entirely made up of full-time professional clubs and players.
