Simmons College is a women's college in Boston, Massachusetts. Simmons was founded by John Simmons in 1899 to educate women in useful professions. Its undergraduate program is single-sex, with 1300 students enrolled in 2004. The graduate schools (Library and Information Science, Social Work, Health Studies, Management, and an Arts and Sciences program which provide degrees in Education, Communications, and Liberal Arts) are mostly co-ed. Although these programs accept men, the fields in which Simmons offers degrees primarily appeal to women. The exception to the coed graduate programs is the School of Management, which provides the world's only MBA for women only.

Simmons is a member of the Colleges of the Fenway consortium.

Simmons alumnae include Nnenna Freelon and Gwen Ifill.
