Redhill (formerly Broughton) is a town in the Mid North of South Australia adjacent to the Broughton River.

Redhill was for many years the terminus of a broad gauge branch railway (now the southern part of the Adelaide-Port Augusta railway line) which was meant to continue to Port Pirie to connect directly with the standard gauge Trans-Australian Railway. The link was completed in 1938, resulting in a rare triple gauge yard. In the 1980s, when more lines were converted to standard gauge, the Redhill line was diverted to Crystal Brook.
