The Leinster Minor Hurling Championship is an annual hurling competition organised by the Leinster Council of the Gaelic Athletic Association since 1928 for the county teams in the province of Leinster in Ireland. As one of the four provincial championships, it is a component of the most prestigious national competition for this age group, the All-Ireland Minor Hurling Championship. The winners of the Leinster final, like their counterparts in the Munster Championship, are rewarded by advancing directly to the semi-final stage of the All-Ireland series of games. The losers of the Leinster final enter the All-Ireland series at the quarter-final stage.
