Donald Ferdinand Kellner (born: September 15, 1879 Ethel, Ontario - April 1, 1935) was a politician from Alberta, Canada.
Kellner was elected as a Progressive to the Canadian House of Commons in the 1921 Canadian federal election in the Edmonton East. He defeated Joseph Clarke and incumbent Henry Arthur Mackie in a 3 way race to serve his first term in office. Kellner switched to the new Athabaska district in the 1925 Canadian federal election. Kellner was defeated by former Alberta Liberal MLA Charles Cross. A year later, in the 1926 Canadian federal election he would end up defeating Cross in a re-match as a member of the United Farmers of Alberta. Kellner would serve out his second term before being defeated by John Francis Buckley in the 1930 Canadian federal election.
