The Isle of Gigha (; ) is a small island off the west coast of Kintyre in Scotland. The island forms part of Argyll and Bute and has a usually resident population of about 160 people. The climate is mild with higher than average sunshine hours and the soils are fertile.
Gigha has a long history, having been inhabited continuously since prehistoric times. It may have had an important role during the Kingdom of Dalriada and is the ancestral home of Clan MacNeill. It fell under the control of the Norse and the Lords of the Isles before becoming incorporated into modern Scotland and saw a variety of conflicts during the medieval period.
The population of Gigha peaked at over 700 in the eighteenth century, but during the 20th century the island had numerous owners, which caused various problems in developing the island. By the beginning of the 21st century resident numbers had fallen to only 98. However a "community buy-out" in 2002 has transformed the island, which now has a growing population and a variety of new commercial activities to complement farming and tourism.
