Tennessee State Route 374 is a west–east state highway in Montgomery County, Tennessee that acts as a cross-town arterial road for travelers in Clarksville, Tennessee. It starts at one end in southeast Clarksville (near Sango) at U.S. Highway 41A, and heads northwest, then west, then south becoming:

The route forms a northern loop around central Clarksville. Warfield Boulevard and Richview Road are both two-lane sections and the 101st Parkway and the Purple Heart Parkway are both four-lane divided highways with partially controlled access, meeting the federal (MUTCD) definition of an expressway. The expressway features three interchanges: a single-point urban interchange with Wilma Rudolph Boulevard US 79, a variation of the partial cloverleaf interchange with Fort Campbell Boulevard (US 41A), and an uncompleted trumpet-like western terminus at Dover Road (US 79)

Warfield Boulevard is named for a family that owned the land before it was constructed there.

Construction is complete along the 101st Parkway segment of SR 374, which widened that part of the highway to four lanes and created an overpass with exits that allow traffic to freely flow over Wilma Rudolph Boulevard. Additional plans call for expansion of Warfield Boulevard on the southwest side of Clarksville sometime in the future and to Palmyra beyond US-79 on the Northwest side of Clarksville. A proposal to extend SR 374 past its current Dover Road terminus, across the Cumberland River to SR 149. A community meeting was held in November 2010, but as of 2012 it appears no further progress has been made.
