The Ivy League is an American collegiate athletic conference of eight private research universities in the Northeastern United States. The term Ivy League is used more broadly to refer to the eight schools that belong to the league, which are globally-renowned as elite colleges associated with academic excellence, highly selective admissions, and social elitism. The term was used as early as 1933, and it became official in 1954 following the formation of the Ivy League athletic conference.
