Dwayne Keith Murphy (born on March 18, 1955, in Merced, California) is a former Major League Baseball player who spent most of his career playing for the Oakland Athletics as an outfielder. He is currently the hitting coach for the Toronto Blue Jays. He was drafted by the Oakland Athletics in 1973 and made his Major League debut in 1978. He spent nine years with the Athletics and played under managers, Billy Martin, Sparky Anderson, and Tony LaRussa. The A's made the playoffs in 1981, where they lost to the New York Yankees in the American League Championship Series. In those playoffs, Murphy hit .421 and hit one home run in six games. Murphy's biggest offensive year came in 1984, where he hit 33 home runs and drove in 88 runs. Murphy also drew many walks, and had excellent speed on the base paths. He stole 26 bases in both 1980 and 1982.

He was also one of the best defensive outfielders of his time, receiving six consecutive Gold Gloves from 1980 through 1985. Murphy had a signature play where his hat blew off his head virtually every time he made a spectacular catch. It occasionally even happened on routine fly balls and it eventually became Murphy's trademark.
