Hunterston B nuclear power station is a shut-down AGR nuclear power station in North Ayrshire, Scotland. Located about six miles (ten kilometres) south of Largs and about 2+1⁄2 miles (4 kilometres) northwest of West Kilbride on the Firth of Clyde coast. It is currently operated by EDF Energy. The station began producing electricity in 1976, and was permanently shut down in 2022.

Hunterston B is similar in design to sister station Hinkley Point B, which ceased operations in August 2022.
