Calve Island is an uninhabited low-lying island off the east coast of the Isle of Mull in Argyll and Bute on the west coast of Scotland. A whitewashed farmhouse with substantial outbuildings stands on the western shore, used as a summer residence. The island is 1+1⁄4 miles in length, and 1⁄2 mile wide at its widest point. Calve is owned by the Cotton family who make use of it in the summer months.
