Thomas Wingett Corbett Jr. (born June 17, 1949) is an American politician, lobbyist, and former prosecutor who served as the 46th governor of Pennsylvania from 2011 to 2015. A member of the Republican Party, he was also attorney general of Pennsylvania. Born in Philadelphia, Corbett is a graduate of Lebanon Valley College and St. Mary's University School of Law and served as a captain in the Pennsylvania Army National Guard. Corbett began his career as an assistant district attorney in Allegheny County, Pennsylvania, in 1976. Corbett then joined the U.S. Department of Justice as an assistant U.S. Attorney for the Western District of Pennsylvania, serving from 1980 to 1983, upon entering private practice. In 1988 Corbett was first elected to public office as a Township Commissioner in the Pittsburgh suburb of Shaler, before serving as the United States Attorney for Western Pennsylvania from 1989 to 1993 in the George H. W. Bush administration. In 1995, Corbett was appointed to fill the remainder of Ernie Preate's term as Attorney General of Pennsylvania, until 1997. Corbett then reentered private practice and worked as the general counsel for Waste Management, Inc before being elected Attorney General of Pennsylvania in 2004. Corbett was then reelected to a second term in 2008, serving a total of two non-consecutive tenures as attorney general from 1995 to 1997, and 2005 to 2011. Corbett was elected Governor of Pennsylvania in 2010, defeating Democratic nominee Dan Onorato in the general election. He was the second Pennsylvania attorney general to win the state's highest office. Corbett lost his bid for a second term to Democrat Tom Wolf in 2014, marking the first time an incumbent Pennsylvania governor lost their reelection bid since William Bigler in 1854, and the first time in history that a Republican governor lost reelection in Pennsylvania. After his defeat, he returned to private life and registered as a lobbyist in 2021. As of 2024, he is the most recent Republican to have served as governor of Pennsylvania.
