Hector Lang (September 5, 1871 – March 11, 1952) was a provincial level politician from Alberta, Canada. He served as a member of the Legislative Assembly of Alberta from 1928 to 1935 sitting with the opposition Liberal caucus.
Lang ran for a seat to the Alberta Legislature in a by-election held in the Medicine Hat electoral district on May 1, 1928. Lang faced three other candidates winning almost 40% to head the polls on the first count. On the second count Lang was just shy of a majority. He won the district on the third count to earn his first term in office and hold the district for the Liberals.[1]
Two years later Lang would run for a second term in office in the 1930 Alberta general election. Like the by-election in 1928 this election would also go to transfers. On the first count Lang nearly won outright winning almost 46% of the vote. He won on the second count after second place choices gave him nearly 60%.[2]
Lang would run for a third term in office in the 1935 Alberta general election. He would be defeated in a landslide by Social Credit candidate John Robinson finishing a distant second in the three way race.[3]
