William Thomas Napier Champ (15 April 1808 – 25 August 1892) was a soldier and politician who served as the first Premier of Tasmania from 1856 to 1857.

Some of the regiment was detached as a garrison force for the Macquarie Harbour Penal Station, Van Diemens Land (now Tasmania) in 1829, and Champ was amongst them.

However, he had apparently enjoyed his time in Australia and later in 1834 he resigned his army commission and returned to Van Diemens Land to enter the civil service.

Champ then became an assistant police magistrate, before being appointed as the commandant of Port Arthur penitentiary (succeeding Charles O'Hara Booth) in 1844.

[1] He later entered politics in Victoria, becoming a member of the Victorian Legislative Assembly for East Bourke Boroughs from April 1871 until May 1873.
