Perimeter College at Georgia State University  is a college of Georgia State University in Atlanta, Georgia.  Georgia Perimeter College was originally a public community college founded by an Atlanta area county board of education before merging with Georgia State University in 2016 to create one of the largest universities in the United States with over 50,000 students. The Perimeter College (PC) campuses became components of Georgia State University, still maintaining their own mission, degrees, and admittance requirements, separate from those of the main campus. Before merging with GSU, PC served metro Atlanta with five campus locations and offered more than 40 programs of study, including Arts, Music, Theatre, Nursing, Business Administration, Education, Dental Hygiene, Criminal Justice, and Sign Language Interpreting.
 Perimeter College was founded by the DeKalb County Board of Education as DeKalb College in 1958 and offered its first classes in Clarkston, Georgia, in 1964.  Its service area grew as new campuses opened and students came to the college from throughout the metro area. In 1997, DeKalb College was renamed Georgia Perimeter College. It was called Georgia Perimeter College, as a two-year associate degree-granting unit of the University System of Georgia until January 6, 2016.
