Peter Nicholson Duckett White (19 January 1936 – 13 February 2005) was an Australian politician. Born in Brisbane, he was educated at Duntroon Military College and the Australian National University in Canberra before serving in the military from 1954 to 1975. In 1977, he was elected to the Queensland Legislative Assembly as the Liberal member for Southport. He held that position until 1980, when he retired in preparation for a run at federal politics in the by-election for the Australian House of Representatives seat of McPherson caused by the death of Liberal minister Eric Robinson. White was challenged by National Country Party Senator Glen Sheil, but won the seat safely. He held the seat until his retirement in 1990. White died in 2005.
