LaMar Baker (December 29, 1915 – June 20, 2003) was a Tennessee businessman and Republican political figure who served two terms in the United States House of Representatives from 1971 to 1975.

In 1970, he received the Republican nomination for the Chattanooga-based Congressional District to replace Bill Brock, who was elected to the United States Senate.

He won a very close race in November, undoubtedly aided by coattails of Brock and the Republican gubernatorial victor, Winfield Dunn.

Baker lost badly in a rematch against Lloyd in 1976, when Jimmy Carter of Georgia won Tennessee's electoral votes.

From 1981 to 1985, during the administration of U.S. President Ronald W. Reagan, Baker served as the regional representative to the United States Secretary of Transportation Drew Lewis.
