Ferbane and Tullamore will return to O'Connor Park for another senior championship decider.
This year's Offaly Senior Football Championship final will be a repeat of last year after both Tullamore and Ferbane came through their semi-finals on Sunday.
Defending champions Tullamore were comfortably better than Edenderry in their last four contest.
An early goal from Cormac Egan set the tone and Tullamore kept Edenderry to just two points in the first period, and three more in the second.
The final score was 2-8 to 0-5.
In the championship's other semi-final, Ferbane proved to be too good for Shamrocks.
The scores were level at the break with Shamrocks enjoying the assistance of a substantial breeze.
Half way through the second half, last year's beaten finalists had opened a seven point lead and saw out the game to win on a final scoreline of 2-13 to 2-7.
