This is a list of combat vehicles of World War I, including conceptual, experimental, prototype, training and production vehicles. The vehicles in this list were either used in combat, produced or designed during the First World War. World War One saw the start of modern armoured warfare with an emphasis on using motor vehicles to provide support to the infantry.

Tanks came about as means to break the stalemate of trench warfare. They were developed to break through barbed wire and destroy enemy machine gun posts. The British and the French were the major users of tanks during the war; tanks were a lower priority for Germany as it assumed a defensive strategy. The few tanks that Germany built were outnumbered by the number of French and British tanks captured and reused.
Most of the armoured cars of the war were produced by building armoured bodywork over commercial large car and truck chassis.
A tank destroyer, tank hunter or tank killer is a type of armoured fighting vehicle, predominantly intended for anti-tank duties. They are typically armed with a direct fire artillery gun, also known as a self-propelled anti-tank gun, or missile launcher, also called an anti-tank missile carrier. The vehicles are designed specifically to engage and destroy enemy tanks, often with limited operational capacities.
A tank is an armoured fighting vehicle intended as a primary offensive weapon in front-line ground combat. Tank designs are a balance of heavy firepower, strong armour, and battlefield mobility provided by tracks and a powerful engine; their main armament is often mounted within a turret. They are a mainstay of modern 20th and 21st century ground forces and a key part of combined arms combat.
The history of the tank includes all vehicles intended to advance under enemy fire while remaining protected.
The Renault FT is a French light tank that was among the most revolutionary and influential tank designs in history. The FT was the first production tank to have its armament within a fully rotating turret. The Renault FT's configuration became and remains the standard tank layout. Consequently, some armoured warfare historians have called the Renault FT the world's first modern tank.
The Type 94 tankette was a tankette used by the Imperial Japanese Army in the Second Sino-Japanese War, at Nomonhan against the Soviet Union, and in World War II. Although tankettes were often used as ammunition tractors, and general infantry support, they were designed for reconnaissance, and not for direct combat. The lightweight Type 94 proved effective in China as the Chinese National Revolutionary Army had only three tank battalions to oppose them, and those tank battalions were equipped only with some British export models and Italian CV-33 tankettes. As with nearly all tankettes built in the 1920s and 1930s, they had thin armor that could be penetrated by .50 caliber (12.7 mm) machine gun fire at 600 yards (550 m) range.
The Schneider CA 1 was the first French tank, developed during the First World War.
The Saint-Chamond was the second French tank to enter service during the First World War, with 400 manufactured from April 1917 to July 1918. Although not a tank by a strict definition of a heavily armoured turreted vehicle, it is generally accepted and described as such in accounts of early tank development. It takes its name from the commune of Saint-Chamond where its manufacturers Compagnie des forges et aciéries de la marine et d'Homécourt (FAMH) were based.
The char 2C, also known as the FCM 2C, was a French post WWI heavy tank landship, later considered a super-heavy tank. It was developed during World War I but not deployed until after the war. It was, in total volume or physical dimensions, the largest operational tank ever made.
The M3 scout car was an American armored car produced in the World War II era, from 1939 to 1944. The original M3 scout car was produced in limited numbers, while the improved M3A1 scout car saw wide service during World War II and after.
The Holt gas–electric tank was the first prototype tank built in the United States in a collaboration between the Holt Manufacturing Company and the General Electric Company. The tank, built during 1917–1918, was the only one of its kind built, as testing proved it lacked the agility and maneuverability required. The crew number is often given as six, on the assumption there would be two machine gunners, a gunner and loader for the main gun, a driver and a commander.
The development of tanks in World War I was a response to the stalemate that developed on the Western Front. Although vehicles that incorporated the basic principles of the tank had been projected in the decade or so before the War, it was the alarmingly heavy casualties of the start of its trench warfare that stimulated development. Research took place in both Great Britain and France, with Germany only belatedly following the Allies' lead.
The Lanchester armoured car was a British armoured car built on the chassis of the Lanchester "Sporting Forty", it saw wide service with the Royal Naval Air Service and British Army during the First World War. The Lanchester was the second most numerous World War I armoured car in British service after the Rolls-Royce armoured car.
The Mortier 280 mm TR de Schneider sur affût-chenilles St Chamond was a French self-propelled siege howitzer designed during the First World War and used during the Second World War.
Renault armoured cars were a number of armoured car variants produced in France during the First World War.
The Seabrook armoured lorry was a British heavy armoured car built on the chassis of an American 5-ton truck which saw service with the Royal Naval Air Service during the First World War.
The White AM armoured car was a French First World War armoured car that was built on a commercial American White Motor Company truck chassis with armoured bodies supplied by the French firm Ségur & Lorfeuvre, it was used by the French military from its introduction in 1915. Between the wars the French military completely rebuilt the vehicles as the White-Laffly AMD 50 and the Laffly-Vincennes AMD 80, in these guises it served until at least 1943.
The Pierce-Arrow armoured AA lorry was a self-propelled anti-aircraft carrier mounting a QF 2-pounder AA "pom-pom" gun, it was used by the Royal Marine Artillery during the First World War.
