Dartmouth College (/ˈdɑːrtməθ/; DART-məth) is a private Ivy League research university in Hanover, New Hampshire, United States. Established in 1769 by Eleazar Wheelock, it is the ninth-oldest institution of higher education in the United States and one of the nine colonial colleges chartered before the American Revolution. Although founded to educate Native Americans in Christian theology and the English way of life, Dartmouth primarily trained Congregationalist ministers during its early history before it gradually secularized, emerging at the turn of the 20th century from relative obscurity into national prominence.

Following a liberal arts curriculum, the university provides undergraduate instruction in 40 academic departments and interdisciplinary programs, including 57 majors in the humanities, social sciences, natural sciences, and engineering, and enables students to design specialized concentrations or engage in dual degree programs. Dartmouth comprises five constituent schools: the original undergraduate college, the Geisel School of Medicine, the Thayer School of Engineering, the Tuck School of Business, and the Guarini School of Graduate and Advanced Studies. The university also has affiliations with the Dartmouth–Hitchcock Medical Center, the Rockefeller Center for Public Policy and Social Sciences, and the Hopkins Center for the Arts. With a student enrollment of about 6,600, Dartmouth is the smallest university in the Ivy League. Undergraduate admissions are highly selective with an acceptance rate of 6.17% for the class of 2025.
