William Rogers (22 July 1818 – 26 August 1903) was a politician in the early days of the colony of South Australia.

William Rogers, a builder and stonemason, emigrated from Cornwall to South Australia on the Platina, arriving in July 1839. He settled in the Sandergrove district, and was responsible for a large number of constructions in the area, including John Dunn's flour mill at Mount Barker. His brother Joseph also emigrated, joining him in 1847.^[1] He acquired some property and began breeding sheep. When William Bowman left the Finniss district around 1878, Rogers purchased his property "View Bank" and later had a share in Portee station on the River Murray near Blanchetown and another at Swan Reach. He made his elder son manager (later owner) of Finniss, and gave Portee and Swan Reach stations to younger son Edwin. They sustained heavy losses in the 1890s drought, but survived and had largely recovered financially at the time of his death.^[2]

He was a member of the first fully elected House of Assembly, representing Mount Barker from September 1858 to March 1860 and June 1864 to March 1865 as a colleague of John Dunn. He held the same seat from May 1868 to August 1868 and November 1868 to April 1870 with John Cheriton then Encounter Bay from February 1872 to February 1875, when his colleagues were in turn Thomas Reynolds and Arthur Fydell Lindsay.^[3]
