William Richard Herrion (born April 6, 1958) is an American college basketball coach. Since 2005, he has been the men's head coach with the University of New Hampshire. Prior to coming to UNH, he served as the head coach at East Carolina University and Drexel University. He has been an assistant with Boston University, George Washington University, and the U.S. National Team.
Bill's brother Tom Herrion formerly served in the NCAA's Division I as the head men's basketball coach at the College of Charleston and an assistant coach at the University of Pittsburgh. Tom is the former head men's basketball coach at the Marshall University.
Herrion began his college coaching career in 1985 as an assistant under Mike Jarvis at Boston University. He followed Jarvis to George Washington University before striking out on his own as a head coach, first at Drexel and subsequently at East Carolina and UNH.
He is one of the most successful men's coaches in the history of the America East Conference. The Drexel Dragons won 3 conference championships in a row under Herrion's leadership from 1994 to 1996. In 1998, on the occasion of the conference's 20th anniversary, he was named one of the four most influential coaches in the conference's history: the other three coaches were Jarvis, Rick Pitino and Hall of Famer Jim Calhoun. He holds the conference record for most playoff wins (18 with Drexel, 1 with UNH, for a total of 19.)
On December 4, 2010, he won his 300th game when UNH beat Colgate, 65-60. His career coaching record, as of the end of the 2010-2011 season, is 308–276.
