William Angus Manson Gunn AM (22 June 1920 – 20 September 2001) was an Australian politician who represented the Queensland Legislative Assembly seat of Somerset from 1972 until 1992.

A member of the National Party, he also served as a Minister and Deputy Premier in various Queensland administrations during the 1980s, and was instrumental in establishing the Fitzgerald Inquiry.

[7] On 23–24 November, Bjelke-Petersen visited the Governor of Queensland Sir Walter Campbell, attempting to have five ministers sacked — including Gunn, for alleged disloyalty in nominating Sparkes as party president — and seeking support for an early election.

The Governor, however, received advice from Gunn and fellow ministers Mike Ahern and Brian Austin that Bjelke-Petersen no longer had parliamentary support.

When the full ministry was sworn in on 9 December, Gunn was appointed Deputy Premier, Minister for Public Works, Main Roads, Police and the World Expo 88 to be held in Brisbane.

Among other things, he was responsible for a multimillion-dollar program to help local councils develop regional road infrastructure, and getting bullet-proof vests as standard issue for police officers.

[citation needed] Gunn's daughter Helen married a successful man from Badu Island, William Bowie.

On 20 September 2001, he died at the Gatton Hospital and was buried privately after a State funeral at the Laidley Cultural Centre six days later.
