William Bowie Stewart Campbell Sawers (1844 – 19 May 1916) was a Scottish-born Australian politician.

Born in Stirlingshire in Scotland, where he was educated, he migrated to Australia in 1865, becoming a grazier with large holdings.

In 1885 he was elected to the New South Wales Legislative Assembly as the member for Bourke, holding the seat until 1886; later, in 1898, he was elected to the seat of Tamworth.

In 1901 he resigned from the Legislative Assembly in order to contest the first federal election as the Protectionist candidate for New England; he won narrowly.
