The Aviatik D.III was a German prototype single-seater fighter plane from the First World War, designed by Aviatik.

In November 1917, the plane was first flown, using a 195 hp Benz Bz IIIbo gearless engine.

It was of similar design to the Aviatik D.II, and was armed with two LMG 08/15 machine guns.

After several tests at Adlershof from February 9–12, 1918, the plane underwent modifications, as requested by the Idflieg.

In April, a second prototype, powered by a Benz Bz IIIbm, although several D.III powered by the original IIIbo engine were already under production;[1] however, none of them were ever completed.
