Walter Hannaford (20 May 1868 – 29 June 1942) was a farmer and politician in South Australia.
Walter was educated at the local school and at Thomas Caterer's College at Semaphore.
As a young man he had a financial interest in a Queensland grazing property, and he took a keen interest in local government there, as well as in the Riverton district, where he was for some time chairman of the District Council of Gilbert.
He was elected to the Legislative Council in 1912, representing the Midland (previously designated "North-East") district, and held it until 1941, when he retired.
Walter Hannaford (20 May 1868 – 29 June 1942), one of many notable descendants of Susannah Hannaford, married Clara Evelyn Bowden (1868–1960) on 23 March 1899, lived at "Broad Oak", Riverton, later "Leiston", Galway Avenue Collinswood.
