The University System of New Hampshire (USNH) operates the state's largest network of public postsecondary institutions, serving approximately 27,000 enrolled students annually across five campuses and sites in every county. The system comprises the University of New Hampshire–Durham, UNH Manchester, Plymouth State University, Keene State College, and the UNH Franklin Pierce School of Law, alongside extensive online learning offerings. Governed by a Board of Trustees with a System Office in Concord, USNH maintains an alumni base of over 90,000 living within the state.
The institution conducts research across multiple domains, including air quality, ocean mapping and oceanography, economic development, family health and public health, and teacher training. These efforts support both academic inquiry and applied work that benefits New Hampshire communities. USNH also operates community outreach and service programs designed to expand knowledge and serve the broader population across the state.
As the primary provider of postsecondary education in New Hampshire, USNH maintains campuses integrated into Durham, Plymouth, and Keene, offering both traditional and online educational pathways. The system's geographic distribution and commitment to accessible education positions it as a significant employer and technology infrastructure operator across the state.
