Lynn A. Westmoreland (b. April 2, 1950, Atlanta, Georgia), a politician from the U.S. state of Georgia, has been a member of the U.S. House of Representatives since 2005, serving as a Republican representing Georgia's 3rd congressional district. The district, which was numbered as the 8th District during his first term, stretches from the far southern Atlanta suburbs to the suburbs of Columbus.

Prior to his election to the United States Congress, Westmoreland owned a construction company and worked as a real estate developer after dropping out of Georgia State University. He also served in the Georgia House of Representatives beginning in 1993 and began serving as the House Republican Leader in 2001, until he resigned from that position to pursue his Congressional campaign in late 2003. He continued to serve in the Georgia House until his election to the U.S. House in 2004.

During his time as the Republican Leader in the Georgia House, he led the fight against redistricting by the Democratic majority in 2001, and then was instrumental in the re-redistricting that took place in 2005 after Republicans won control of the Georgia legislature in the 2004 elections.
