James Bernard Williams (born May 15, 1926 in Toronto) is a Canadian former outfielder, coach and manager in minor league baseball and coach in Major League Baseball. Williams threw and batted right-handed, stood 5'10" (178 cm) tall and weighed 180 pounds (82 kg). He is a member of the Canadian Baseball Hall of Fame.

Williams graduated from Toronto's De La Salle College School, where he played varsity baseball, hockey (as a right wing), football and lacrosse.

He played in the farm system of the Brooklyn/Los Angeles Dodgers in 1947-64. Although he never was called to the majors as a player, Williams enjoyed several highly productive seasons. In his first year as a professional, split between three Dodger farm teams in the lower minors, Williams batted a composite .367 with 15 triples, 121 runs batted in, 24 stolen bases and 12 home runs. He played three seasons (1955-57) of Triple-A baseball in his native Canada with the Montreal Royals of the International League, batting .329 in 1955 with 93 runs scored, 33 doubles, eight triples, 13 homers, and 21 stolen bases, and also exceeded the .300 mark with the 1958 Spokane Indians of the Pacific Coast League.

His playing got him noticed by the minor leagues, and he went on to enjoy a lengthy career as a manager in minor league baseball in 1963-80, where he compiled a record of 1,155 wins and 1,156 defeats (.499). His seventeen years of managing in the minors was interrupted by a brief period of coaching with the Major-League Houston Astros for a season in 1975. His most significant achievement was his coaching tenure with the Baltimore Orioles (1981-87), a run that included their historic 1983 World Series win. Williams then followed former Baltimore general manager Hank Peters to the Cleveland Indians, where Williams served as director of field operations for the club's farm system.

Jimmy Williams lives in retirement in Maryland. He is not to be confused with James Francis "Jimy" Williams (born 1943), also a former minor league skipper and Major League coach and former manager of the Astros, Toronto Blue Jays and Boston Red Sox.
