The Research Triangle, or simply The Triangle, are both common nicknames for a metropolitan area in the Piedmont region of the U.S. state of North Carolina. Anchored by the cities of Raleigh and Durham and the town of Chapel Hill, the region is home to three major research universities: North Carolina State University, Duke University, and the University of North Carolina at Chapel Hill, respectively. The "Triangle" name originated in the 1950s with the creation of Research Triangle Park located between the three anchor cities, which is the largest research park in the United States and home to numerous high tech companies.
