William Oliver Archibald was an Australian politician. He was a member of the South Australian House of Assembly from 1893 to 1910, representing Port Adelaide, and a member of the Australian House of Representatives from 1910 to 1919, representing Hindmarsh. Archibald was a Labor member until resigning in the 1916 Labor split; he subsequently served as a Nationalist until his defeat at the 1919 federal election.

The Division of Hindmarsh is an Australian Electoral Division in South Australia covering the western suburbs of Adelaide. The division was one of the seven established when the former Division of South Australia was split on 2 October 1903, and was first contested at the 1903 election, though on vastly different boundaries. The Division is named after Sir John Hindmarsh, who was Governor of South Australia from 1836 to 1838. The 78 km2 seat extends from the coast in the west to South Road in the east, covering the suburbs of Ascot Park, Brooklyn Park, Edwardstown, Fulham, Glenelg, Grange, Henley Beach, Kidman Park, Kurralta Park, Morphettville, Plympton, Richmond, Semaphore Park, Torrensville, West Beach and West Lakes. The Adelaide International Airport is centrally located in the electorate, making noise pollution a prominent local issue, besides the aged care needs of the relatively elderly population − the seat has one of Australia's highest proportions of citizens over the age of 65. Progressive boundary redistributions over many decades transformed Hindmarsh from a safe Labor seat in to a marginal seat often won by the government of the day.
