Ballylahan Castle is a shattered tower house in County Mayo. It is listed as a National Monument.
The main entrance was in the east and it was flanked by two circular towers, of which only one remains. The entrance gives access to an irregular hexagonal bawn. There is evidence of buildings particularly against the western wall. The bawn has some good base-batter, particularly at the northwest corner.
