Avon was an electoral district of the Legislative Assembly in the Australian state of Western Australia from 1911 to 2008. The name of the district was changed to Avon Valley in 1950, but reverted to its original name in 1962. Avon was abolished when the number of rural seats was reduced as a result of the one vote one value reforms. Almost all of its area moved into the new seat of Central Wheatbelt.
