The Tri-Cities is the region comprising the cities of Kingsport, Johnson City, and Bristol and the surrounding smaller towns and communities in Northeast Tennessee and Southwest Virginia. All three cities are located in Northeast Tennessee, while Bristol has a twin city of the same name in Virginia.

The Tri-Cities region was formerly a single Metropolitan Statistical Area (MSA); due to the U.S. Census Bureau's revised definitions of urban areas in the early 2000s, it is now a Combined Statistical Area (CSA) with two metropolitan components: Johnson City and Kingsport–Bristol, TN–VA. [1] However, the Tri-Cities are usually still considered one population center, which is the fifth-largest in Tennessee.
