Dublin scored a 2-13 to 1-13 win over Meath to retain their Leinster SFC title in front of a crowd of 69,656 at Croke Park.
Bernard Brogan returned to form with a 1-7 tally as the Dubs held on for a place in the All-Ireland quarter-finals.
Early scores from the Brogan brothers, Bernard and Alan, gave Dublin a positive start, before Brian Farrel led Meath's revival with three points as they narrowed the gap to two.
But two goals in the space of a minute, from Bernard Brogan and Denis Bastick, sent the Dubs in with a 2-7 to 0-5 interval lead.
Dublin opened out a nine points lead, but Jamie Queeney blasted home a Meath goal to narrow the gap to three.
The Royals pressed in the closing stages for a second goal, but the champions' defence held firm.
Donegal made history by retaining the Ulster SFC title for the first time with a 2-18 to 0-13 win over Down at Clones.
It was another hugely impressive performance from the men from the north-west, whose much-maligned defensive approach has evolved into a wonderfully effective attacking strategy.
Down had no answer to the power and pace of Donegal's counter-attacks in the second half, after turning around just a point in arrears at the break.
