Samuel Mitchell (c. 1838 – 5 July 1912) was an Australian businessman and politician who was a pioneer of the mining industry in Western Australia.

He served as chairman of the roads board from 1876 to 1879, and eventually left the mining business, settling down in Northampton as a storekeeper, stock agent and Justice of the Peace.

[7] At the 1897 state election, Mitchell was returned to parliament as a member of the Legislative Assembly, representing the seat of Murchison.

[8] At the 1904 state election, both Mitchell and Nanson contested the seat of Greenough, which was adjacent to Murchison but considered more winnable.

[9] Mitchell published an autobiography in 1911 (Looking Backwards: Reminiscences of Forty-Two Years), and died at his home, Chiverton House, Northampton in July 1912.
