The All-American Girls Professional Baseball League (AAGPBL) was a professional women's baseball league founded by Philip K. Wrigley, which existed from 1943 to 1954. The AAGPBL is the forerunner of women's professional league sports in the United States. Over 600 women played in the league, which eventually consisted of 10 teams located in the American Midwest. In 1948, league attendance peaked at over 900,000 spectators. The most successful team, the Rockford Peaches, won a league-best four championships.

Women's baseball is played in several countries. The strongest and most organized women's baseball leagues are in the United States, Australia, Japan, Taiwan, Cuba, Hong Kong, and Canada. Those countries have national governing bodies that support girls' and women's baseball programs. Other countries/regions that currently have organized women's baseball are Germany, France, Netherlands, Croatia, India, South Korea, Venezuela, Argentina, Puerto Rico, Colombia, Brazil, Dominican Republic, and Pakistan. There also is a handful of women playing baseball in Vietnam currently on the Fishanu team at Hanoi University and on the Hanoi Baseball Club.
