William Charles Campbell Bignall Robinson (4 October 1907 – 21 January 1981) was a British-born Australian politician.

Robinson enlisted in the Royal Australian Air Force during World War II, serving as a mechanic from 1942 to 1945.

After a brief post-war return to his old role at Wandering, he was secretary of the Pingelly Road Board from 1946 to 1974, having been granted a leave of absence during his Senate term.

Robinson was secretary of the Wandering and Pingelly branches and the Narrogin district council of the Country and Democratic League, a member of the wool committee and political executive of the Primary Producers' Association of Western Australia and secretary of the Pingelly Agricultural Society.

He was preselected in the unwinnable fourth position on the combined Liberal-Country ticket for the 1953 election, but was defeated.
