Wesley Branch Rickey Jr. (January 31, 1914 – April 10, 1961) was an American front office executive in Major League Baseball. The son of Baseball Hall of Fame club executive Branch Rickey, who among his many achievements invented the farm system and led the movement within baseball to break the color line, Branch Jr. — called "The Twig" by many — was a highly respected farm system director, but never led his own organization. He was the father of Branch Barrett Rickey, widely known as "Branch Rickey III", a longtime baseball executive and the last president of the Pacific Coast League.
