For the Senior equivalent see: Connacht Senior Hurling Championship The Connacht U-21 Hurling Championship is an U-21 hurling tournament.

The last winners of the Connacht championship was Galway in 2005, there was no competition in 2006 and 2007 therefore Galway went straight to the semi-finals of the All-Ireland Under-21 Hurling Championship without playing a game.

Galway are the only team to win the Connacht championship and it has only been played on 8 occasions due to a lack of a competitive side to compete with in Connacht.

[citation needed] The competition was resurrected in 2010 as part of the All-Ireland B Under-21 Hurling Championship.

The final was won by Roscommon who defeated Mayo 3–10 to 0–10.
