The electoral district of Capel was a Legislative Assembly electorate in the state of Western Australia. The district was named for the South West town of Capel, located between Bunbury and Busselton, which fell within its borders. The seat was abolished after only one term at the 2007 redistribution, taking effect from the 2008 election due to the one vote one value legislation. Most parts of the seat now fall within the new seat of Collie-Preston, which is regarded as a marginal Labor seat by Antony Green based on 2005 figures, with the Busselton portions becoming part of Vasse.
