The Williams Club is in residence at the Penn Club of New York for alumni of Williams College. Until 2010, it was its own private club. The Williams Club was founded in 1913 by Williams alumni in New York City as a place to socialize. The club was originally located at 291 Madison Avenue in a building donated by Mary Clark Thompson, wife of Williams alumnus Frederick Ferris Thompson. In 1921, it moved to 24 East 39th Street in Manhattan, which it then renovated in 1988. On June 1, 2010, however, the Williams Club ceased operating on its own and moved its membership program and related activities to the Princeton Club. After the permanent closure of the Princeton Club in fall 2021, the Williams Club moved to the Penn Club. Today, members and their guests can use the Penn Club's facilities.
