Inch Kenneth (Scottish Gaelic: Innis Choinnich) is an uninhabited island off the west coast of the Isle of Mull, Scotland. Its lies to the south east of Ulva. The island is named after St Kenneth, who founded a monastery on the island, the remains of which still stand. There is also a large mansion there. It was visited by Samuel Johnson and James Boswell during their tour of the Hebrides, when it belonged to a laird of the Maclean clan.
The island was once owned by Sir Harold Boulton, the writer of the words to the Skye Boat Song. Its most famous owners were the eccentric Mitford family. Nazi sympathiser Unity Mitford spent her final years living on the island. It passed in the 1960s to her sister Jessica, a former communist, who teasingly suggested that it might become a Soviet submarine base.
The area of Inch Kenneth is 55 hectares - about a fifth of a square mile.
