Republic of Ireland National League Women

The FAI/WFAI first organised a women's national league in 1973. It was known as the Ladies League of Ireland or the Woman's League of Ireland. Twelve teams were originally invited to participate. These included several teams associated with clubs in the men's League of Ireland such as Dundalk, Finn Harps, Cork Celtic, Limerick and Sligo Rovers. Others included Benfica (Waterford), Evergreen (Kilkenny), Avengers (Dublin), Cahir Park (Tipperary) and three teams from Galway – Beejays, Happy Wanderers and Wasps. The league started in March 1973 and teams played thirty five minute halves. As the league got started, there were some changes and dropouts. Cahir Park defeated Elms United, a fourth team from Galway, 1–0 at West Park, Galway, in the very first Ladies League of Ireland game on Sunday, 4 March 1973. Evergreen (Kilkenny) withdrew after losing their first three games, although a Kilkenny team did compete in the 1974 season. Benfica played an away game at Finn Harps as part of a double header before a 1972–73 League of Ireland game between Finn Harps and Waterford. Limerick finished the 1973 season as champions after going unbeaten in a fifteen match series. In a post season friendly they lost 3–1 to a touring Stade de Reims at Markets Field.

By 1979 the Ladies League of Ireland featured seven teams with approximately 120 active players. The original Ladies League of Ireland subsequently went into demise but was relaunched in April 1987. This time its members included Cork Rangers, Cork Celtic, Benfica, Greenpark (Limerick) and Dublin Castle and games featured forty minute halves. Eamonn Darcy, a former manager of the Republic of Ireland women's national football team, served as vice-president of the league. The revived league was sponsored by Hotpoint and Cork Rangers were the 1987 champions. Dublin Castle were the 1988 champions after defeating Greenpark (Limerick) 3–1 in a play-off. However the revived Ladies League of Ireland lasted just three seasons and was abandoned in 1989.

In 1996 there was an unsuccessful attempt to launch a third Ladies League of Ireland. Proposed members included a Mayo Ladies League representative team and Longford Strikers. During the 1990s and 2000s, in the absence of an official national league, the Dublin Women's Soccer League developed into a de facto national league. The Women's Soccer Colleges Association of Ireland (WSCAI) also organised a national league featuring women's teams representing universities and third level colleges from both the Republic of Ireland and Northern Ireland. Both of these leagues featured future members of the Women's National League. Peamount United, Raheny United, Shamrock Rovers and Shelbourne Ladies were all members of the DWSL while UCD fielded teams in both leagues.

The current Women's National League was formed in 2011–12. Originally seven clubs were invited to join the league. These included Peamount United, Castlebar Celtic, Cork Women's F.C., Raheny United, Shamrock Rovers, Wexford Youths and Bray Wanderers/St. Joseph's. The league was launched with financial support from UEFA. Twenty-six clubs had originally applied to join the league before the final seven were chosen. However, due to a lack of playing resources, Bray Wanderers/St Joseph's had to withdraw before the season started. Peamount United were the inaugural league champions, finishing three points clear of second placed Raheny United. Peamount United also completed a league double by winning the WNL Cup, defeating Shamrock Rovers 1–0 in the final. The following two seasons, 2012–13 and 2013–14, saw Raheny United finish as league champions. The league received international publicity in October 2013 when Stephanie Roche scored an acclaimed goal for Peamount United against Wexford Youths which subsequently went viral on YouTube. Footage of the goal was uploaded to the internet by team manager Eileen Gleeson as the matches were not televised. Together with James Rodríguez and Robin van Persie, Roche was subsequently nominated for the 2014 FIFA Puskás Award. At the 2014 FIFA Ballon d'Or awards ceremony on 12 January 2015, Roche finished second to Rodríguez with 33% of the vote. In 2014–15 Wexford Youths were league champions and in 2015–16 they retained the title after defeating Shelbourne Ladies in a play-off.

In 2016 a shortened transitional season was played from August to December where each team played 14 matches. From 2017 the league was restructured into a summer league, while a possible new team from Sligo entered into talks to join.

The league celebrated its 10th year in 2021 with a new sponsor (SSE Airtricity). This was the first year it shared the same sponsor as the men's League of Ireland.
