The Dodge WC-54, Ambulance, 3⁄4-ton, 4 x 4, (SNL supply catalog designation G-502), was the main military ambulance variant of the prolific Dodge WC series of light 4×4 trucks, developed during World War II. Built from 1942 until 1945, they served as the U.S. Army's main dedicated ambulance (besides the many multi-purpose jeeps serving as such), with many also serving in the Korean War, in the U.S. Army Medical Corps, some used as late as 1953; and others serving as late as the 1960s in the armies of some European countries.

The 3⁄4‑ton WC-54 was designed as successor to the previous 1/2-ton, 4×4, G-505 models WC-9, WC-18, and WC-27 Dodge Ambulance trucks.^[2] Although based on the 3/4-ton Dodge "Beep" chassis, which front and rear axles featured wider tracks of 64+3⁄4 in (1.64 m), the 3/4-ton ambulance versions retained a longer wheelbase, very close to that of the previous half-tonners, as well as somewhat rounded, upward sloping nose sheetmetal, instead of the fully horizontal, flat and wider engine-cover of the main 3⁄4‑ton redesigned WC-models.^[3] The WC-54s also had adjusted suspension to make their ride softer.

The closed sheet-metal body was made by Wayne Body works. It had room for a driver and four to seven patients plus a medic. If the fold-away bunk stretchers were used, four patients could be transported lying down.^[2] Because of its intended role, the WC-54 featured a large matrix cab heater fitted on the inner firewall, providing comfort for patients and crew. It was fitted with a foldaway step to its rear to allow easier access for stretcher bearers and injured personnel. Early models featured a stuck out fuel filler cap which was changed to a recessed one in the later model, a modification that was retrofitted to some early model trucks.

From 1942 to 1945, total production of the 3/4-ton Dodge WC-series was some 255,000. Of these, 29,502 were ambulances — 26,002 WC‑54 and 3,500 WC-64 KD models.^[1][4] The vehicles were supplied under US government contracts W398-QM-11420 (850 units), W398-QM-11422 (9,945 units), DAW398-QM-448 (16 units), W398-QM-13596 (410 units) and W374-ORD-2864 (11,636 units).^[2]
