Thomas Richard "Tom" Carper (born January 23, 1947) is the senior United States Senator from Delaware and a member of the Democratic Party. He was previously the 71st Governor of Delaware and a member of the House of Representatives from Delaware.

A native of Danville, Virginia, Carper graduated from the Ohio State University. Serving as a Naval Flight Officer in the U.S. Navy from 1968 until 1973, he saw active duty in the Vietnam War. He remained in the U.S. Naval Reserve for another 18 years and retired with the rank of Captain. Upon receiving his MBA from the University of Delaware in 1975, Carper went to work for the State of Delaware in its economic development office. He was elected State Treasurer, serving from 1977 to 1983 and leading the development of Delaware's first cash management system.

Encouraged by local politicians, Carper successfully ran for Delaware's only seat in the U.S. House of Representatives in 1982. He served five terms in the House, where he chaired the Subcommittee on Economic Stabilization. In 1992 he arranged a "swap" with term-limited Governor Michael Castle, and the two were easily elected to each other's seats. Carper governed for two terms as a moderate, business-oriented "New Democrat", following the lead of the two previous Republican governors. He successfully prevented the closing of a General Motors automobile plant and won a bid for the headquarters of pharmaceutical giant AstraZeneca. He led a tax-reduction campaign and helped improve the state's credit rating from among the worst in the nation to an excellent "AAA". He pushed for standards-based education, among other reforms.
