Lady Barbara Montague (ca. 1722 – August 1765) was a British philanthropist and charity worker, who sponsored programs to assist primarily poor women. As an unmarried woman, and due to illness unable to live with family, she created an alternate family situation that allowed her independence. Joining a community of women in Bath, the group pooled their resources to provide support for each other and others in their community. Upon her death, she left bequests to continue providing for those who had been important in caring for her in her lifetime.
