Inchcailloch (Gael. innis-eailleach, ' island of the nun '), a hilly, wooded island of Buchanan parish, Stirlingshire, in Loch Lomond, between Torrinch and Balmaha, 7 furlongs NW of the mouth of the river Endrick. With an utmost length and breadth of 6½ by 3 furlongs, it belongs to the Duke of Montrose, and till 1621 was the seat of Inchcailloch parish church, dedicated to St Kentigerna, a holy woman who had dwelt here as an anchorite. The foundations of this church (57 x 24 feet) may still be traced; whilst its ancient graveyard is still in use, and contains some curious 17th century tombstones-Ord. Sur., sh. 38, 1871. See Dr William Fraser's The Lennox (1874).
