The Sullivan Museum and History Center is the official museum of Norwich University, named for GEN Gordon R. Sullivan, USA (Ret.) '59. Located in Northfield, Vermont, and opened in 2007, the facility is 16,000 square feet and includes both permanent and changing exhibits featuring items and exploring themes from the 200-year history of the school and from broader American military history, through the lens of Norwich staff, students, and friends' experiences and accomplishments in both the military and private spheres, along with rotating artists' exhibits and student work. It the first museum in Vermont to be affiliated with the Smithsonian Institution, allowing the museum to access Smithsonian collections and material to provide more offerings to the public than it could on its own.

The Sullivan Museum and History Center's collection ranges from uniforms of university alumni to fine art, folk art, Norwich University ephemera, and more. As of March 2023, the museum collection numbered over 20,000 objects including audio-visual materials documenting the university for nearly 100 years.

The museum presents exhibits about the university's history and its military ties.
