William Adolphus Chaffey (2 February 1915 – 4 March 1987) was an Australian farmer, soldier and member of the New South Wales Legislative Assembly for the district of Tamworth (1940–1973). He also served as the New South Wales Minister for Agriculture from 1965 to 1968.
William Adolphus Chaffey was born in Tamworth, New South Wales on 2 February 1915 to Frank Augustus Chaffey, himself a member of the New South Wales Legislative Assembly, and Amy McIlveen. He was educated at Tamworth public school, The King's School, and Hawkesbury Agricultural College.
On 16 December 1941 he joined the Australian Imperial Force. He served in the 2/5th Independent Company, and was twice mentioned in despatches, as well as winning the United States' Bronze Star Medal. In 1948, he became a member of the Australian Citizens Military Forces, remaining there until 1961.
On 29 January 1946 William Adolphus Chaffey married Patricia Egerton-Warburton at Mount Barker. They would eventually have two daughters and one son.
On the death of his father, Frank Augustus Chaffey, William succeeded to his father's seat, as a member of the United Australia Party. In 1941 and 1944, he was re-elected as an independent, after losing the United Australia Party pre-selection. From 1947 to 1972, he was a member of the Country Party. After an ideological split in 1972, he continued his term as an independent. From 1959 to 1968, Chaffey was deputy leader of the Country Party.
