The Division of Boothby is an Australian federal electoral division in South Australia. The division was one of the seven established when the former Division of South Australia was redistributed on 2 October 1903 and is named after William Boothby (1829–1903), the Returning Officer for the first federal election.

The Division of South Australia was an Australian electoral division covering South Australia. The seven-member statewide seat existed from the inaugural 1901 election until the 1903 election. Each elector cast seven votes. Unlike most of the other states, South Australia had not been split into individual single-member electorates. The other exception was the five-member Division of Tasmania. The statewide seats were abolished at a redistribution conducted two months prior to the 1903 election and were subsequently replaced with single-member divisions, one per displaced member, with each elector now casting a single vote.
