The Boston Breakers were an American professional women's soccer club based in the Boston neighborhood of Allston. The team competed in the National Women's Soccer League (NWSL). They replaced the original Breakers, who competed in the defunct Women's United Soccer Association, as the Boston area's professional women's soccer team. Boston would eventually get a new expansion team in 2023 that would begin play in 2026.

The National Women's Soccer League (NWSL) is a professional women's soccer league at the top of the United States league system. Headquartered in New York City, it is owned by the teams and, until 2020, was under a management contract with the United States Soccer Federation.
