A V18 engine is an eighteen-cylinder piston engine where two banks of nine cylinders are arranged in a V configuration around a common crankshaft.
The V18 engine is a rare configuration and is primarily used in large diesel engines running at low operating speeds. These large V18 diesel engines have seen limited use in haul trucks, electricity generation, rail transport, and marine propulsion.
There are no known automobiles that have used V18 engines and no engine manufacturer has developed or produced a V18 engine for use in automobiles.
While the V18 is a more uncommon engine configuration, there are more common eighteen-cylinder engine configurations such as the W18, which has seen use in both automobiles and aircraft, and the Deltic, an opposed-piston eighteen-cylinder diesel engine created by D. Napier & Son which was used for a variety of applications.

| Cummins QSK78[2] | Script error: No such module "convert". | Script error: No such module "convert". | Diesel | Derived from the V16 QSK60.[2] Marketed by Komatsu as the SSDA18V170.[3] |
| Fairbanks Morse Colt-Pielstick PC2.5 | 63,510 cu in (1,040 L) | 11,700 hp (8.73 MW) | Diesel | In production |
| MAN V32/44CR | 39,055 cu in (643 L) | 14,483 hp (10.8 MW) | Diesel | In production |
| Wärtsilä 18V50DF[4] | Script error: No such module "convert". | Script error: No such module "convert". | Diesel or natural gas |
Available for both marine propulsion and power generation, and used in e.g. Humboldt Bay power station.[5] |
| Paxman Valenta 18RP200 | 7,230 cu in (118.44 L) | 4,901 hp (3,655 MW) | Diesel | Out of production, used for marine propulsion and power generation.[6] |
The BelAZ 75600 and Liebherr T 282B haul trucks are powered by the Cummins QSK78 engine, while the Komatsu 960E-1 haul truck is powered by the Komatsu SSDA18V170 engine.
In 1971, the Canadian locomotive manufacturer MLW-Worthington produced the MLW M640 prototype diesel-electric locomotive powered by a Script error: No such module "convert".ALCO 18-251 engine, however the locomotive did not reach production.
