Chattanooga State Community College (informally Chatt State) is a public community college in Chattanooga, Tennessee. The college is a member of the Tennessee Board of Regents System and is accredited by the Southern Association of Colleges and Schools (SACS). Athletically, Chattanooga State is a member of Region VII of the NJCAA.

Chattanooga State is the only community college in Tennessee that has a Tennessee College of Applied Technology (TCAT) as an integral part of its organization. The TCAT offers 21 diploma programs and 7 certificate programs with a combined annual enrollment of over 2,300 students and has 1151 employees.

Chattanooga State functions as an open-entry postsecondary institution for students residing in six counties in Southeast Tennessee, as well as seven bordering counties of North Georgia and Northeast Alabama, including Bledsoe, Grundy, Hamilton, Marion, Rhea, and Sequatchie in Tennessee; Catoosa, Dade, Fannin, Murray, Walker, and Whitfield in Georgia; and Jackson in Alabama.

In the early 1960s, the Tennessee State Board of Education began efforts to establish community colleges across the state as a result of post-World War II children entering higher education. In September 1965, Chattanooga State became Tennessee's first technical college and Southeast Tennessee's first public institution of higher education. It was originally known as Chattanooga State Technical Institute and was classified as a two-year, coeducational, college-level institution. The college was founded to offer technical programs with Associate in Science and Associate in Engineering degrees, primarily to meet industry needs and "to bridge the gap between engineers and craftsmen."

In 1973, Chattanooga State Technical Institute became Chattanooga State Technical Community College. Specifics of Senate Bill 1010 mandated that the college provide comprehensive one and two-year occupational, college parallel, continuing education, and community service programs; offer quality technical and scientific occupational programs; and serve as a regional technical school to train engineering technicians or technical workers in the fields of production, distribution, and service.

The college was under the State Board of Education until 1974 when it became part of the State Community College and University System, which was later renamed the Tennessee Board of Regents. With that administrative change the college identified the counties in its service area: Hamilton, Rhea, Bledsoe, Sequatchie, Marion, and Grundy counties in Tennessee and border counties in Georgia.

In 1981, the State Area Vocational-Technical School, now known as the Tennessee College of Applied Technology (TCAT), entered into a pilot merger with Chattanooga State Technical Community College. Consequently, the college added vocational education to its mission. In July 1983 the Tennessee legislature officially recognized the merger, creating a unique partnership between vocational and career programs. With this merger the college began offering one-year certificates in fields such as industrial electronics, automotive technology, and welding.

In 2009, the college was renamed Chattanooga State Community College when Senate Bill 681 became law.
