St Ronan's 1-10 Rice College 1-09
St Ronan's, Lurgan are the All-Ireland champions for the first time.
The County Armagh school edged out Rice College, Westport in the Hogan Cup final by a point in a thrilling final at Croke Park in Dublin.
Oisin Smyth slotted home the winning point from wide on the right side, a stunning strike worthy of winning an All-Ireland final.
St Ronan's had trailed by two points at half-time but shot back through Tiernan Kelly's second half goal to tee up Smyth's point that sealed a deserved victory.
Smyth scored four points on the day, converting St Ronan's first two of the day before three Eoin McConville 45 metre frees also flew over the bar.
However, a fortunate Rice College goal had helped to give the Westport side a two-point advantage at half-time.
Roighan Meehan and Adam Loughran (2) were also among the points for a St Ronan's side that always looked stronger and in the end were able to hold possession in the closing stages to see out the narrowest of victories.
