Trine University is a postsecondary educational institution based in Angola, Indiana, United States. It has satellite campuses in South Bend/Mishawaka, Schererville, Logansport, Indiana, Indianapolis, Howe, Columbus Warsaw, and Fort Wayne. Trine was founded in 1884 as Tri-State Normal College, and retained the reference to the "Tri-State" area for more than 120 years — so named because of the school's proximity to three different states. Angola, where the main campus is located, is less than 10 miles from the Michigan border and also nearly 10 miles from the Ohio state line. In 1906, just 22 years later, it was renamed Tri-State College. Much later, in 1975, it was renamed to Tri-State University (TSU). Satellite campuses were opened in other Indiana locations throughout the 1990s. Then, in 2008, it was renamed as Trine University to remove any reference to a state-funded institution and the Tri-state area, and to honor alumnus Ralph Trine. The main campus covers 400 acres (1.6 km²) in Angola, Indiana. There is another campus for the School of Professional Studies in Angola, as well as other satellite campuses in South Bend/Mishawaka, Indiana, Merrillville, and Fort Wayne.
