The Ivy League is an American collegiate athletic conference comprising eight private research universities in the Northeastern United States. The term Ivy League is typically used beyond the sports context to refer to the eight schools as a group of elite colleges with connotations of academic excellence, selectivity in admissions, and social elitism. Its members are Brown University, Columbia University, Cornell University, Dartmouth College, Harvard University, Princeton University, University of Pennsylvania, and Yale University.

While the term was in use as early as 1933, it became official only after the formation of the athletic conference in 1954. All of the "Ivies" except Cornell were founded during the colonial period; they thus account for seven of the nine colonial colleges chartered before the American Revolution. The other two colonial colleges, Rutgers University and the College of William & Mary, became public institutions.
