The electoral region of Agricultural is a multi-member electoral region of the Western Australian Legislative Council, located in the South West, Peel and part of the Great Southern regions of the state. It was created by the Acts Amendment (Electoral Reform) Act 1987, and became effective on 22 May 1989 with five members who had been elected at the 1989 state election three months earlier. At the 2008 election, it was increased to six members.
Since its creation, the electorate has had 25 members, only seven of whom were or are not from either the Liberal or National parties. All five of the members elected in 1989 had previously been members of the Legislative Council.
3 Frank Hough was elected as a One Nation member, but resigned from the party on 1 June 2004 and sat as an independent. He later co-founded the New Country Party, and represented them in the Council until the end of his term.
