The Rumpler G.I was a bomber aircraft produced in Germany during World War I, together with refined versions known as the G.II and G.III.

The engines were mounted pusher-fashion in nacelles atop the lower wings and enclosed in streamlined cowlings.

[2] The G.II version was almost identical, but featured more powerful engines and carried a second 7.92 mm (.312 in) machine gun and increased bombload.

[2] The G.III was again similar, but had engine nacelles that were now mounted on short struts clear of the lower wing.

K = Kampfflugzeug (battleplane), renamed as G-class, L = bomber midway between K/G and R-classes
