Mosman Park is a western suburb of Perth, Western Australia on the north bank of the Swan River in the local government area of the Town of Mosman Park. It was historically known as Buckland Hill (1889-1909), then Cottesloe Beach (1909-1930) and again Buckland Hill (1930-1937). From 1937 it was named Mosman Park, derived from Mosman in Sydney, the birthplace of Richard Yeldon, a member of the Buckland Hill Road Board. Mosman Park is now considered an affluent suburb, but prior to the 1970s was one of Perth's major industrial centres.
In 2010 the Australian Bureau of Statistics announced that Mosman Park had the second highest average value for private sector houses in 2008-09, at $1.579 million, ahead of Mosman in Sydney, which had the highest average value houses in New South Wales at $1.373 million.
