St Mary's Old Church is a roofless ruin in the hamlet of Kilmuir, just outside Dunvegan. It was completed in 1694, replacing an older medieval church that served as the parish church for the Duirinish region of northern Skye.

It is the final resting place of several chiefs of the Clan Macleod, along with generations of MacCrimmons, hereditary pipers to the Macleods.
