The Junior League in New Jersey
Since its founding in 1901 by social activist Mary Harriman, the Junior League has grown into one of the oldest, largest, and most impactful women’s volunteer organizations in the world. Today, it comprises over 125,000 women across more than 290 Leagues in four countries. For over a century, the Junior League has been at the forefront of social reform, addressing critical issues such as pollution, illiteracy, domestic violence, and supporting foster children in need of a safety net.

Mary Harriman, inspired by the social challenges she observed in New York City, sought to prove that women could bring about meaningful change in society through collective social responsibility.

Built on the pillars of volunteerism, community leadership, and social reform, the Junior League has since evolved into the Association of Junior Leagues International (AJLI), with a mission to develop women’s civic leadership and promote volunteerism in communities across the United States and around the world.

​All Junior Leagues are members of the Association of Junior Leagues International.
