John Hill (c. 1810 – 11 August 1860) was an English explorer of South Australia and part of the European exploration of Australia. Hill was the first European to see and traverse the Clare Valley. An enigmatic and little-known individual, during the late 1830s John Hill sighted and named several important rivers of South Australia, as well as many lesser streams and creeks. The former unquestionably include the Wakefield and Hutt rivers, plus (most probably) the Gilbert and Light rivers. He was also the first European to explore the headwaters of the Torrens and Onkaparinga rivers.
