Kerrera is an island in the Scottish Inner Hebrides, close to the town of Oban. In 2005 it had a population of about 35 people, and it is linked to the mainland by passenger ferry on the Gallanach Road.

The island is known for the ruined Gylen Castle, built in 1582. It was also the place where Alexander II of Scotland died in 1249. The highest point on Kerrera is Carn Breugach at 189 metres (620 ft). Most of the island is owned by the McDougalls of Dunollie, who are descended from the Scottish prince Somerled. The four-acre tidal island at the north-east tip of Kerrera, Rubh'a Chruidh, was sold for £426,000 in 2010 to Lanarkshire businessman, David Hamilton.

The main industries on the island are farming (sheep and Highland cattle) and tourism. There is a tea room/café at the south end near Gylen Castle. The castle itself has recently been restored and is now fully open to the public. At the north end of the island is the 200-berth Oban Marina, which has a complementary ferry service running to/from North Pier, Oban. The only licensed premises on the island is situated here; the Waypoint Bar and Grill which sells local produce including oysters, scallops, beef and lamb.
