Maurice Joy Conner (November 30, 1868 – May 9, 1937), sometimes spelled Maurice Joy Connor,[1] 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 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.

In 1928, Conner abstained from voting on the Sexual Sterilization Act, introduced by Premier John Edward Brownlee's UFA government, and was the only UFA member present not to support the bill.
