William "Willie" Ferguson (6 March 1940, Johannesburg – 19 May 2007, Durban) was a racing driver from South Africa. He entered the 1972 South African Grand Prix with local outfit Team Gunston, running a Brabham BT33, but could not start the race due to a blown engine in practice. He was also pencilled in to drive a Surtees TS9 for the same team, but that car was eventually raced by John Love. Ferguson participated in numerous non-Championship Formula One races.
