State Highway 394 is a 9.2 mi (14.8 km) long state highway in northwestern Colorado.

SH 394 begins at a junction with U.S. Highway 40 at Craig and proceeds eastward roughly parallel to US 40. The highway nominally ends after 9¼ miles at the county line between Moffat County and Routt County. The road continues east to rejoin US 40 at Hayden, however, from the county line eastward, the road is not a part of the state highway system and portions of the route are unimproved.

The entire route is in Moffat County.
