Pollagh, also spelled Pullough, is a village in County Offaly, Ireland, located in the midlands of Ireland. It is a rural village on the Grand Canal and lies between Ferbane and Tullamore. Much of the surrounding area is bogland, and is used to produce fossil fuels such as peat turf. The River Brosna flows close to the village. The Grand Canal was used for transporting peat and bricks produced in the area. Pollagh benefited from the canal in earlier years when it brought investment and employment from Bord na Móna, and it is now a tourist attraction. Pollagh is also known for its church, including its bog oak altar and stained glass windows, designed by the Harry Clarke studios.
