The Connacht Senior Hurling Championship, known simply as the Connacht Championship, was an annual inter-county hurling competition organised by the Connacht Council of the Gaelic Athletic Association (GAA). It was the highest inter-county hurling competition in the province of Connacht, and was contested almost every year between 1900 and 1922 before a revival in the 1990s.
The final served as the culmination of a series of games played during the summer months, and the results determined which team received the M. J. "Inky" Flaherty Cup. The championship was always played on a straight knockout basis whereby once a team lost they were eliminated from the championship.
The Connacht Championship was an integral part of the wider All-Ireland Senior Hurling Championship. The winners of the Connacht final, like their counterparts in the other provincial championships in Leinster, Munster and Ulster, advanced directly to the semi-final stage of the All-Ireland series of games.
The title was won at least once by three of the Connacht counties; however, only Galway won the title more than once. The all-time record-holders are Galway, who won the championship on 25 occasions.
As one of the weakest of the four provincial championships, the championship was suspended from 1923 to 1993, with Galway representing the province in the All-Ireland Championship. A brief revival in 1995 failed to reinvigorate hurling in the province and the Connacht Championship was abolished following the 1999 championship.
