William Harry Laxton (born January 5, 1948) is an American former Major League Baseball pitcher.

He was traded to the Philadelphia Phillies in December 1967 along with Harold Clem, Woodie Fryman, and Don Money in exchange for future-Hall of Famer Jim Bunning.

He signed with the New York Mets, who subsequently traded him to the Detroit Tigers along with Rusty Staub in exchange for Mickey Lolich and Billy Baldwin on December 12, 1975.

[4][5] Laxton pitched the top of the ninth, and the Mariners scored two in the bottom of the inning for a come-from-behind, 7–6 win over the California Angels.

Laxton's son, Brett, pitched in the major leagues in 1999–2000 for the Oakland Athletics and Kansas City Royals.
