State Route 193 is an east and west highway located completely in Davis County, Utah, United States that begins at the West Davis Corridor, runs past the south entrance of Hill Air Force Base and ends at US-89.

East of the interchange, Hill Air Force Base borders the northern side of the road and the highway enters Layton.

The route intersects with the northern terminus of SR-232 at Hill Field Road, which also provides access to the south gate of the air force base.

The highway approaches the eastern edge of Layton and terminates at a diamond interchange with US-89 at Exit 404.

[3] Despite the original definition, the road was built with federal aid in 1940 and 1941 past Hill Air Force Base, with a western terminus at SR-1 in Clearfield; a separate route - SR-232 - was similarly built in 1940 and numbered in 1941,[4] running north from Layton to SR-193 at Hill Field.
