The Seven Sisters schools are American all-women colleges who organized in 1927 to better promote female education. These are:

Two of the Seven Sisters, Mount Holyoke and Smith, are members of the Five Colleges.

1978 marked a historic milestone, when all Seven Sisters finally had women presidents.

Not all of the Seven Sisters remain all-female colleges. Vassar began accepting men in 1969. In 1963, Harvard College assumed joint responsibility with Radcliffe over Radcliffe undergraduates. In 1999 Radcliffe College was dissolved, and Harvard assumed full responsibility over the affairs of female undergraduates. Radcliffe is now the Radcliffe Institute for Advanced Study in women's studies and part of Harvard University.
