The Leichter Kampfwagen (English: light combat vehicle) or "LK I" was a German light tank prototype of the First World War. Designed to be a cheap light tank as opposed to the expensive heavies coming into service at the time, the tank only reached the prototype stage before the end of the war.

The LK I was designed by Joseph Vollmer. It was based on a Daimler car chassis, using the existing axles to mount sprocket and idler wheels. Its design followed automobile practice, with a front-mounted engine and a driving compartment behind it. It was the first German armored fighting vehicle to be equipped with a turret, armed with a 7.92 mm MG08 machine gun.

Only two prototypes were produced in mid 1918, but no vehicles were ordered.^[1] Designed as an experimental cavalry tank, it paved the way to the LK II.^[2]
