State Route 193 is an east and west highway located completely in Davis County, Utah that begins at SR-126, runs through the south entrance of Hill Air Force Base and ends at US-89.

SR-193 begins at the intersection of Main Street and Bernard Fisher Highway in Clearfield and heads east on the latter as a four-lane undivided highway through suburban Clearfield. After a couple of intersections with local roads and passing to the north of a park, the road intersects with I-15 at exit 334, a diamond interchange. Past this interchange, Hill Air Force Base appears on the northern side of the road and the highway enters Layton. Soon, the route intersects with the northern terminus of SR-232, which continues north to the south gate of Hill AFB. Past the southeastern fringe of the base, the road turns to the southeast before intersecting with Church Street, where SR-193 turns northeast again. The highway approaches the eastern edge of Layton and intersects at a diamond interchange with US-89 at exit 404.

The state legislature created SR-193 in 1935, running northeast from SR-1 (now SR-126) in Layton to SR-49 (now US-89). 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, running north from Layton to SR-193 at Hill Field. The definition of SR-193 was corrected to reflect its new route in 1945.
