The Albatros G.I (post-war company designation L.4) was a four-engined German biplane bomber of World War I.

at Schneidemühl by Otto Wiener and Dr. Walter Huth, the OAW maintained close ties with Albatros, remaining an independent company until October 1917.

The majority of OAWs work involved licence manufacture of products from the parent Albatros company.

The G.I was of typical construction for 1915, with wooden structure, wire-braced and covered with fabric and four engines mounted in nacelles on the lower wing upper surface.

The later G.II and G.III were not directly related to the G.I, being twin-engined, a lot lighter and having completely different wing designs.
