Lieutenant Colonel Robert William Bonner QC (10 September 1920 – 12 August 2005) was a Canadian lawyer, politician, and corporate executive.

He would retain the position of Attorney General for the next sixteen years, quickly becoming one of the most powerful ministers and closest advisors to Bennett in the Socreds' long spell of governance.

Bonner's tenure as Attorney General was marked by legal clashes with First Nations tribes over land and resource rights, especially in light of the rapid hydroelectric, mining, and forestry development of the province's hinterland.

Perhaps more significantly, from a historical perspective, was the provincial government's conflicts with the Freedomites (Sons of Freedom), an anti-government religious group resident in the Kootenay region of the province.

Bonner left Mac Blo in 1976 to become chairman of BC Hydro, the provincial crown corporation responsible for producing and supplying hydroelectric power.
