Damastown (Irish: Baile Dama) is a townland in the civil parish of Mulhuddart in Fingal, Ireland. The townland is located west of the village of Mulhuddart and is north of the N3 road. A 1.8 km (1.1 mi) link road is nearing completion to link Damastown to the Cruiserath Road intersecting Church Road which links Mulhuddart to Tyrrelstown. A temporary recycling centre was set up in Damastown to allow for an upgrade to the Coolmine recycling centre.
