Clonrush or Clonmulsk (Irish: Cluain Rois[1]) is a civil parish in the barony of Leitrim, now in County Clare, Ireland.

[2] The Clonrush graveyard was established around the 12th century in an early Christian settlement on a ridge beside Church Bay in Lough Derg.

A portion of the building remains, including a 12th-century window in the east gable, restored in the 16th century with cut limestone.

The graveyard contains a small vaulted house called St. Colman's Oratory, with a Gothic doorway from the 16th century.
