Research Triangle Park (RTP) is the largest research park in the United States, occupying 7,000 acres (2,833 ha) in North Carolina and hosting more than 300 companies and 65,000 workers. It is owned and managed by the Research Triangle Foundation, a private non-profit organization.

North Carolina's Research Triangle region is named for the facility, which sits within the geographic triangle formed by three nearby research universities: North Carolina State University, Duke University, and University of North Carolina at Chapel Hill.

The park is bounded by the cities of Raleigh, Durham, and Chapel Hill and the communities of Morrisville and Cary. Most of its territory lies within Durham County, with about one-quarter in Wake County.
