Is knoxvill Tennessee in southern Tennessee?

Not quite. It is more Northeast than anything else. Memphis and Chattanooga is in South Tennessee, Clarksville and Nashville is in North Tennessee, Kingsport and Bristol is in East Tennessee and West Tennessee contains Jackson, Dyersburg and part of Memphis. Look up a map of Tn(Tennessee) and you will see for yourself the area of Tennesse Knoxville is in.

Hope it helped!
