Maurice Joy Conner, sometimes spelled Maurice Joy Connor, was a Canadian politician who served as the member of the Legislative Assembly of Alberta for Warner from 1921 until 1935. Before entering politics, he was a Methodist preacher in the United States. He first sought office in the 1921 Alberta provincial election as a candidate for the United Farmers of Alberta (UFA) in Warner. He defeated Liberal incumbent Frank Leffingwell and became one of 38 UFA candidates elected as the party, which was contesting its first election, won a surprise majority government. He was re-elected in the 1926 and 1930 elections, and did not seek re-election in the 1935 election, when the UFA lost every seat and the new Social Credit League won a majority.

The 1921 Alberta general election was held on July 18, 1921, to elect members to the 5th Alberta Legislative Assembly. It was one of only five times that Alberta has changed governments.
