Robert Phillips "Bob" Corker, Jr., (born August 24, 1952) is the junior United States Senator from Tennessee. Before his election to the Senate in 2006, he served as mayor of Chattanooga from 2001 to 2005. Corker was a successful businessman prior to holding public office.

Born in Orangeburg, South Carolina, Corker moved to Tennessee at the age of 11. He graduated from Chattanooga High School in 1970. He earned a Bachelor of Science degree in Industrial Management from the University of Tennessee, Knoxville in 1974. He and his wife Elizabeth, whom he married on May 18, 1987, have two daughters. The family's permanent residence is at the Anne Haven mansion built by Coca-Cola Bottling Company heirs Anne Lupton and Frank Harrison.

After working four years as a construction superintendent, he started his own construction company, Bencor, which he sold in 1990. In 1999, he purchased the two largest real estate companies in Chattanooga, Osborne Building Corporation and the Stone Fort Land Company, making him the largest private land owner in Hamilton County, Tennessee. He sold most of these holdings in 2006 to Henry Luken. His business successes have made Corker a multimillionaire. Corker's assets are estimated at $19.19 million in 2008.
