Jack Ginifer

John Joseph "Jack" Ginifer (31 August 1927 – 9 July 1982) was an Australian politician.

Ginifer was born in Warracknabeal, Victoria to Joseph Ginifer, a Singer sewing machine salesman from England, and Agnes Harper. He was educated at schools in Benalla, then undertook teacher training at Melbourne Teachers' College and a Bachelor of Arts at the University of Melbourne. He worked as a schoolteacher for more than twenty years from 1945 to 1966, including at Jamieson St Primary School in Warrnambool.

Ginifer was active in local government politics, serving as a councillor in the Williamstown City Council (1955–1957) and the Shire of Altona (1960–1969). He was also on the state executive of the Labor Party from 1959 to 1966. In 1966, Ginifer was elected at a by-election to the Victorian Legislative Assembly as a Labor member for the seat of Grant. Electoral redistributions saw his seat renamed Deer Park in 1967 and Keilor in 1976.

Ginifer railway station in St Albans, J. J. Ginifer Reserve in Altona North, Jack Ginifer Reserve in Gladstone Park, and Ginifer Court, a cul-de-sac in St Albans, were named after him.
