There are four Provinces in Ireland, each of which has or had its own Softball League, beginning with the Leinster Softball League which started in 1989, following on from the Dublin Softball League which played from 1982 to 1989. The Ulster Softball League started in 2009 and is still playing. The Munster Softball League played from 2011-2014, and the Galway Softball League (Connacht) started in 2020, growing out of the Galway Softball Trophy which played in the 2010s.
Softball Munster existed from around 2010 to 2011 when Limerick Originals and Cork Hammerheads were the backbone of a Munster Softball League which also included Galway Tribes, West Clare Dolphins and Kerry Green Sox
