The Women's Irish Hockey League is a field hockey league organised by Hockey Ireland that features women's teams from both the Republic of Ireland and Northern Ireland. The league was first played for during the 2008–09 season. It replaced the All-Ireland Club Championships as the top level women's field hockey competition in Ireland. Since 2015–16 the league has been sponsored by Ernst & Young and, as a result, it is also known as the EY Hockey League. The league has previously been sponsored by the ESB Group and Electric Ireland.
