John Anthony Barrasso III (/bəˈrɑːs/ bə-RAH-soh; born July 21, 1952) is an American physician and politician serving as the senior United States senator from Wyoming, a seat he has held since 2007. A member of the Republican Party, he served in the Wyoming State Senate from 2003 to 2007. As Chair of the Senate Republican Conference since 2019, he is the third-ranking Senate Republican.

Born and raised in Reading, Pennsylvania, Barrasso graduated from Georgetown University, where he received his B.S. and M.D. He conducted his medical residency at Yale University before moving to Wyoming and beginning a private orthopedics practice in Casper. Barrasso was active in various medical societies and associations.

Barrasso first ran for U.S. Senate in 1996, narrowly losing the Republican primary to Mike Enzi. In 2002, he was elected to the State Senate, where he stayed until his appointment to the U.S. Senate after the 2007 death of Craig L. Thomas. He was elected to finish Thomas's term in 2008 and won his first full term in 2012. In 2018, Barrasso was selected as chair of the Senate Republican Conference. He is the dean of Wyoming's congressional delegation.
