Simmons College is a liberal arts women's college in Boston, Massachusetts. Simmons was founded by John Simmons in 1899 to educate women in useful professions, so they could have an independent livelihood. Simmons is a member of the Colleges of the Fenway consortium which also includes Emmanuel College, Wentworth Institute of Technology, Wheelock College, and Massachusetts College of Art.

Its undergraduate program is single-sex, with 1800 students enrolled in the 2004-2005 academic year. Male relatives of staff members may attend the undergraduate college up to a certain credit limit, although they cannot receive Simmons diplomas.

The graduate schools (Library and Information Science, Social Work, Health Studies, Management, and an Arts and Sciences program which provide degrees in Education, Communications, Gender and Cultural Studies and Liberal Arts) are mostly co-ed. The exception to the coed graduate programs is the School of Management, which provides the world's only MBA for women only.

Simmons alumnae include Nnenna Freelon, Gwen Ifill, Denise DiNovi, Elinor Lipman, Ann Fudge, Rebecca Miller Sykes, Lonnie Barbach, Sage Vivant, Audra Mika, and Suzyn Waldman.

Simmons faculty include Nancy Bond, winner of a Newbery Honor, who taught at the Simmons College Center for the Study of Children's Literature from 1979 to 2001.

In 2006, the college's Board of Trustees elected Dr. Susan C. Scrimshaw to be the college's next president, following an 11-month search. Scrimshaw officially took office on July 1, 2006. She succeeded Daniel S. Cheever, Jr., who, according to the Chronicle of Higher Education, , he received a total compensation of $2,860,686 in his final year of service, the third highest of any college or university president in the United States.
