John Joseph Barry was an American shortstop, second baseman, and manager in Major League Baseball, and later a college baseball coach. From 1908 through 1919, Barry played for the Philadelphia Athletics (1908–1915) and Boston Red Sox (1915–1919).

The Philadelphia Athletics were a Major League Baseball team that played in Philadelphia from 1901 to 1954, when they moved to Kansas City, Missouri, and became the Kansas City Athletics. Following another move in 1967, the team became the Oakland Athletics. In 2025 the franchise will move temporarily to Sacramento before permanently moving to Las Vegas.
