Three Rivers Community College (or TRCC) is a community college in Norwich, Connecticut, USA, formed in 1992 by the merger of Mohegan Community College and Thames Valley Community Technical College. It is named after the three major rivers in the region: the Shetucket, the Yantic and the Thames. It is accredited by the New England Association of Schools and Colleges. The College was split between the Mohegan and Thames Valley campuses on opposite sides of Norwich. In 2003, the state legislature approved funding to consolidate the College at the Thames Valley campus. In 2009, the college finally consolidated into the one campus on New London Turnpike. There are also two off-campus instructional centers, one at the nearby Naval Submarine Base, the other at Ella Grasso Technical School in Groton.
