The George Mason University Arlington Campus is located in Arlington County, in what Arlingtonians call Virginia Square.
In 1979, the Arlington Campus was created when the Commonwealth of Virginia General Assembly authorized George Mason University to establish a law school in the building formerly known as the Kann's department store. The following year the university established the graduate and continuing education programs and fine arts gallery at the Arlington Campus.

In 1996, ground was broken for construction of the first phase of a three phase campus redevelopment project on the Arlington Campus. Completed in the fall of 1998, Hazel Hall (formerly known as the houses the School of Law, the Mercatus Center and the Institute for Humane Studies.

Plans for the Arlington Campus call for two additional phases of construction to accommodate the projected student enrollment of 10,000. The funding for the Phase II project, consisting of 250,000 square feet, was approved by Virginia voters as part of the 2002 Bond Referendum. This phase of the campus development will provide space for the School of Public Policy, the College of Education and Human Development, the School of Information Technology and Engineering, the School of Management, the Institute for Conflict Analysis and Resolution, the School of Computational Science, the College of Visual & Performing Arts and academic and student support services. In addition the building will feature a 300 seat auditorium, a scenic public plaza, a 500 seat multipurpose room and two levels of underground parking. Occupancy is anticipated for 2008.

The Phase III, A and B buildings will replace the original Kann’s Department Store building bringing the entire Arlington campus to a total of 750,000 square feet of space with tremendous opportunity for continued student enrollment, research and support services growth.

The George Mason University Foundation (GMUF) is also contributing to the growth of the Arlington Campus by assisting the University with its campus development mission and commitments to Arlington County. The GMUF constructed a building inclusive of parking to support the university’s parking requirements at the completion of the physical redevelopment of the Arlington Campus. The GMUF building will include parking, 192,000 square feet of office space, and 13,000 square feet of retail space.

In addition to the current facilities and future building plans at the Arlington campus, the University is leasing approximately 18,000 square feet of space in the Truland Building. The Truland Building currently houses the Arlington Campus Administrative offices, the Student Health Services office, academic units and research programs associated with the Institute for Conflict Analysis and Resolution, the Graduate Social Work Program, Interdisciplinary Center for Economic Science and the Washington Legal Clinic.
