Francis Austin Walker (November 17, 1871 – May 29, 1956) was a Canadian politician who served as a member of the Legislative Assembly of Alberta from 1905 until 1921. Born in Lucan, Ontario, on November 17, 1871, he moved west to Alberta, becoming a pioneer in the area east of Edmonton.
In the 1905 provincial election, Alberta's first as a province, Walker ran as the Liberal candidate in the district of Victoria. He was elected by a wide margin to the 1st Alberta Legislature over his opponent Jack Shera who had previously represented the district in the Legislative Assembly of the Northwest Territories. He was re-elected by acclamation in the 1909 election, and was easily re-elected in the 1913 election. Prior to the 1917 election, the legislature passed an act re-electing all of its members serving in the First World War; as Walker was at this time a lieutenant in the Canadian Expeditionary Force, he was thus "re-elected" without need of an election.
In the 1921 Alberta general election Walker was defeated by William Fedun of United Farmers of Alberta.
