Swarthmore College ( SWORTH-mor, locally SWAHTH-mor) is a private liberal arts college in Swarthmore, Pennsylvania, United States. Founded in 1864, with its first classes held in 1869, Swarthmore is one of the earliest coeducational colleges in the United States. It was established as a college under the Religious Society of Friends. By 1906, Swarthmore had dropped its religious affiliation and officially became non-sectarian.

Swarthmore is an exclusively undergraduate four-year institution. It is a member of the Tri-College Consortium, a cooperative academic arrangement with Bryn Mawr College and Haverford College. Swarthmore is also affiliated with the University of Pennsylvania through the Quaker Consortium, which allows students to cross-register for classes at all four institutions.

Swarthmore's alumni include six Nobel Prize winners, thirteen MacArthur Foundation fellows, as well as winners of the Tony Awards, Grammy Awards, Academy Awards, Emmy Awards, and the Guggenheim Fellowship.
