The Toyota ToyoAce is a light to medium cab over truck built by Toyota since September 1954. Until a renaming contest in 1956, the truck was sold as the "Toyopet Light Truck SKB". Since 1985 the ToyoAce and Dyna truck lines have been merged, with the Dynas generally being intended for heavier duty work. In Japan, it is exclusive to Japanese Toyota dealerships called Toyopet Store.

The first-generation ToyoAce was a one-ton truck of a semi-cab over design. It has a four-cylinder sidevalve inline-four "type S" engine of 1.0 L (995 cc) and 30 PS (22 kW). It was originally sold as the "Toyopet Light Truck", a not very inspired name which was changed for "ToyoAce" after a public contest in 1956. The spartan interior featured hammock-style seats, as in a Citroën 2CV. The "K" in the model code was shared, as was the chassis, with the Toyopet SK/RK Truck, a line which was later to become the Toyota Stout. The first Toyoace initially sold slowly, due to a price much higher than the three-wheeled trucks with which it was competing. After a large drop in price, however, the ToyoAce went on to change the Japanese market for light trucks in favor of four-wheeled vehicles.

There were also panel van, light van, double cab and other body styles developed. These received chassis numbers from SK17 to SK19. In 1958 power of the S engine was increased to 33 PS (24 kW). The former Central Motors produced the ToyoAce van from June 1956 to July 1960.

The semi-cab over layout was retained for the second-generation Toyopet ToyoAce, initially sold as the SK20. The new SK20 was also sold as a panel van (SK20V) and as a double-cab truck (SK20P). The sidevalve 1 liter engine's power remained 33 PS (24 kW), as for its predecessor. It was introduced in March 1959, but already by October that year it underwent a facelift and received a new engine, the 1.0-liter 45 PS (33 kW) P type. This was the PK20 series. Australian versions were badged as a Toyota 25. Later yet, 1.25 and 1.5 ton versions were added, with more powerful 1.2 (2P) and 1.5-litre (R) engines. This picture is a PK3# with two single lights, the upgrade added in 1966 was the PK4# series which was fitted with the R engine. After the initial S-engined series, there were only PK models even though they were being powered both by the P and R series engines. This was to set it apart from the Stout which used the "RK"-series chassis numbers. After the 1967 facelift, when the car received quad headlights, a 3P-engined (1.35 L, "PK32") version was added.
