The Tennessee Board of Regents is a system of community and technical colleges in the U.S. state of Tennessee. It is one of two public higher education systems in the state, the other being the University of Tennessee system. It was authorized by an act of the Tennessee General Assembly passed in 1972. The TBR supervises all public community colleges and technical colleges in the state, serving over 110,000 students annually.

A university system is a set of multiple affiliated universities and colleges that are usually geographically distributed. Typically, all member universities in a university system share a common component among all of their various names. Usually, all member universities of a university system are governed by a system-wide governing body, such as a board of trustees or a board of regents. In the United States, many states have one or two state university systems under which many of their publicly funded universities are aligned, both in name and in governance. Additionally, for-profit universities, such as DeVry University, often have multiple campuses which share the same name; these may be, but are not always, described as a university system.
