Frederick Graham Pratten (13 December 1899 – 18 December 1977) was an Australian politician.
Born in Sydney, he attended North Sydney Grammar School and the University of Sydney, and served in World War I 1917–18.
He then became the managing director of the family companies.
In 1928 his uncle, Herbert Pratten, a Nationalist MP, died, and Frederick was selected by the Nationalists to replace him in the resulting by-election for the seat of Martin.
He was elected, and was returned in the federal election later that year.
He was defeated in the elections of 1929.
He was subsequently a member of the New South Wales Legislative Council from 1937 to 1976 and a company director in Sydney.
