The Old North Building, or simply Old North, is the oldest extant academic building on the campus of Georgetown University in Washington, D.C., and was the second major building built on the campus. To the east, the building is joined to Healy Hall and to the west, it is joined to New North, while the southern façade of the building encloses Dahlgren Chapel. Built in the Georgian style, Old North was one of the grandest buildings in Washington at the time of its completion in 1795. It served as the flagship of the university until the construction of Healy Hall. Old North currently houses the McCourt School of Public Policy.

Healy Hall is a National Historic Landmark and the flagship building of the main campus of Georgetown University in Washington, D.C., United States. Constructed between 1877 and 1879, the hall was designed by Paul J. Pelz and John L. Smithmeyer, both of whom also designed the Thomas Jefferson Building of the Library of Congress. The structure is named after Patrick Francis Healy, who was the President of Georgetown University at the time.
