The Connacht Intermediate Championship was introduced in 2005 for teams deemed not eligible for the senior grade.

Prior to 2008, county champions competed in the senior grade, but since then the senior champions from Mayo, Roscommon and London (since 2018) compete at intermediate level along with the Galway intermediate champions, who receive a bye to the final.

Tooreen are the most successful team in the championships history, having won it 5 times.

Beginning with the 2018 championship, the London champions compete in the competition, entering at the semi-final stage.
