Ben Reddin’s injury-time goal capped a frantic end to the game, as the reigning Leinster champions were beaten.
Dublin had led for most of the game, but Laois hung on before producing some exceptional hurling in the last ten minutes.
The first half had been a closely fought affair as there was never more than a score between the teams. Dublin led by two at the break, 0-10 to 0-8, but were lucky to do so after Stephen Maher had seen his penalty saved.
The second half was real end to end stuff, with Neil Foyle’s goal after 42 minutes giving Laois a huge boost.
The teams were level at the end of normal time, but a wonderful point from Foyle edged Laois in front, and Reddin’s goal capped a wonderful night for the O’Moore men.

Wexford, with Gary Moore racking up eight points, powered to a comprehensive victory over Offaly in the Leinster U21 HC quarter-final at O’Connor Park, Tullamore last night.
Aidan Hanrahan’s Offaly side led 0-2 to no score after five minutes but they had little to cheer afterwards as the visitors led 0-9 to 0-5 at the interval.
Offaly registered the opening points through Adrian Hynes (free) and Tom Carroll, however the home side quickly lost their way as Mark Maloney and inter-county footballer Lee Chin began to gain the upper hand around midfield.
Tony Dempsey’s Wexford charges reeled off eight unanswered points between the ninth and 25th minutes, with Jack Guiney contributing three excellent points from frees, while Chin, Barry Carton (two), Moore and Michael O’Regan also chipped in.
Offaly ended the opening half with points from Stephen Quirke, Hynes (free) and Tom Spain to leave them 0-5 to 0-9 adrift at the interval.
Wexford continued to dictate on the resumption and on four separate occasions went seven points ahead.
It was 0-17 to 0-10 with 55 minutes gone before they put the icing on the cake with late points from Chin and Moore and a brilliantly executed Aidan Nolan goal.
Scorers for Offaly: S Quirke 0-3, A Hynes 0-3 (3f), T Carroll 0-2, T Spain, A Kelly 0-1 each.
Scorers for Wexford: G Moore 0-8 (3f), J Guiney 0-4 (4f), Aidan Nolan 1-0, B Carton 0-3, L Chin 0-2, M O’Regan, J Hobbs 0-1 each.
