The Upper West Province was a two-member electoral province of the Western Australian Legislative Council, located in the Mid West region of the state. It was one of several rural seats created following the enactment of the Constitution Acts Amendment Act (No.2) 1963, and became effective on 22 May 1965.
In 1989, the province was abolished by the Acts Amendment (Electoral Reform) Act 1987, and was absorbed into the Mining and Pastoral region under the new proportional voting system.
The province was made up of three complete Legislative Assembly districts, which changed at each distribution.
