Light Regional Council is a local government area north of Adelaide in South Australia. It is based in the town of Kapunda, and includes the towns of Freeling, Greenock, Hansborough, Hewett, Roseworthy and Wasleys. The council is named for the River Light, the south bank of which forms much of the council area's northwest border. The river is named after William Light, the first Surveyor-General of South Australia.
