Barton Jennings "Bart" Gordon, (born January 24, 1949) is a United States Representative from Tennessee, representing the state's 6th Congressional district (map). He is a Blue Dog Democrat. The district includes several rural areas and fast-growing suburbs east of Nashville. With the Democrats' victory in the 2006 midterm elections, Gordon has been named as chairman of the House Committee on Science and Technology. Gordon announced on December 14, 2009 that he would not seek re-election in 2010 and will be retiring from the U.S. Congress at the end of the current term to spend more time with his young daughter.

Gordon was born in Murfreesboro, Tennessee, where he has lived all of his life. He served in the United States Army Reserve in 1971 and 1972. He graduated from Middle Tennessee State University in 1971, earning a law degree from the University of Tennessee in 1973. He then entered private practice in Murfreesboro.

Active in Democratic politics early on, he was briefly executive director of the Tennessee Democratic Party in 1979 and state party chairman from 1981 to 1983. When 6th District Congressman Al Gore announced in 1983 that he would run for the United States Senate in 1984, Gordon stepped down as state party chairman to run for the seat. He initially faced a hard-fought race against the brother of the publisher of Nashville's former conservative newspaper, the Nashville Banner. However, he won handily in November 1984, riding Gore's coattails in the midst of Ronald Reagan's landslide victory in that year's presidential election. Gordon is regarded as a moderate. He has favored the repeal of the inheritance tax and the "marriage tax penalty".
