New Circle Road, also known as Kentucky Route 4, is a Kentucky state highway that serves as an inner beltway around Lexington, which is part of the consolidated city-county government with Fayette County.

The state designates the start and finish of the road at its interchange with Nicholasville Road on the city's south side. Exit numbering increases as one travels clockwise.

Roughly three-fourths of the highway is limited-access, with all movements controlled at 10 interchanges. The remainder is classified as an urban principal arterial highway with a heavy mix of driveway entrances and intersections with one single-point urban interchange at US 60 (Winchester Road) and a diverging diamond interchange at US 68 (Harrodsburg Road). The dividing line between the limited-access segment and the urban arterial highway is US 25 (Richmond and Georgetown Roads) north and east of the city. The speed limit is 55 mph (89 km/h) on the freeway section and 45 mph (72 km/h) on the urban arterial highway.

New Circle Road suffers serious traffic congestion during rush hour due to the lack of other freeways running through the city. Harrodsburg Road, Nicholasville Road, Tates Creek Road, and Newtown Pike also suffer serious congestion because of people trying to get on New Circle and head out of downtown Lexington.
