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 1921 Alberta general election Walker was defeated by William Fedun of United Farmers of Alberta. In that election the Liberal party was swept from power. Walker contested the Victoria seat once again in the 1926 Alberta general election, but was defeated by United Farmers candidate Rudolph Hennig.
