The name Ring IV (Finnish: Kehä IV, in spoken language often kehä nelonen ) refers to the fourth hemicircular road around Helsinki, capital of Finland. Running in the municipalities of Kirkkonummi, Espoo, Vantaa, Tuusula and Sipoo, it has two road number designations: north of Main Road 3 it is Regional Road 104, otherwise Regional Road 152.
The status of the road is that of a highway, not of an expressway. However, for most of its path it resembles an expressway, with at least 2 lanes to each direction, and interchanges.
