Washington University in St. Louis (WashU) is a private research university in St. Louis, Missouri, United States. Founded in 1853 by a group of civic leaders and named for George Washington, the university spans 355 acres across its Danforth and Medical campuses. It comprises nine schools and offers more than 150 undergraduate, 80 master's and professional, and 50 doctoral degree programs. As of 2024, Washington University enrolled 16,399 students representing all 50 U.S. states and more than 110 countries.
Established due to a concern of a lack of institutions of higher learning in the Midwest, the university held its first classes in 1854 in downtown St. Louis. In 1905, Washington University relocated to a new campus northwest of Forest Park, which allowed for expansion and new facilities to support its growing academic programs and student body. Construction of the first building, Busch Hall, began in 1900, followed by Brookings Hall, Ridgley, and Cupples. These buildings were not occupied until 1905 in order to accommodate the 1904 Summer Olympics and St. Louis World's Fair. By 1964, more than two-thirds of incoming students came from outside the St. Louis area. In 2021, the university adopted a need-blind undergraduate-admissions policy.
