Edenderry is a town in north County Offaly, Ireland. It is near the borders with Counties Kildare, Meath and Westmeath. The Grand Canal runs along the south of Edenderry, through the Bog of Allen, and there is a short spur to the town centre.
The R401 road from Kinnegad to the north and the R402 from Enfield to the east meet at the northeastern end of the Main Street. At the Grand Canal they split, with the R402 continuing westwards towards Tullamore and the R401 heads south to Rathangan and Kildare Town.
