William Harrison Myers (August 14, 1910 – April 10, 1995) was an American shortstop in Major League Baseball who played from 1935 through 1941 for the Cincinnati Reds (1935–1940) and Chicago Cubs (1941).

Myers hit .313 for Triple-A Columbus in 1934 before joining Cincinnati in 1935, to become the Reds' starting shortstop for the next six seasons and served as their team captain.

A valuable defensive player, he was recognized as a master of reading baserunners' intents and picking up hit-and-run and stolen base signs from opposing teams.

But Myers is best remembered for his game-winning sacrifice fly in Game 7 of the 1940 World Series against Detroit.

During the 1939 and 1940 pennant-winning seasons, he was also a part of the Reds' "Jungle Club" infield and was nicknamed "Jaguar" by teammate Billy Werber.
