Highway 33 is a road on St. Thomas in the U.S. Virgin Islands. It runs from Highway 30 near Frenchtown and takes a northerly path toward Crown Mountain. The road takes a circuitous route around the mountain; the route initially bypasses it to the west, then swings east and follows the mountain's north side. Highway 33 then intersects Highway 333, which provides access to St. Thomas' north and east sides, and it takes a southeasterly turn to meet Highway 40. Highway 33 continues east-southeast, intersecting Highway 379 before ending at Highway 35.

Highway 33 takes a long path around three sides of Crown Mountain. This section can be bypassed by a short stretch of Highway 332 and Highway 405; however, those roads are rather twisty and can be dangerous, which may be why the longer piece of road was designated Highway 33.
