The Albatros B.I, was a German military reconnaissance aircraft designed in 1913 and which saw service during World War I.
The Albatros B.I was a large three-bay biplane designed with some input by Ernst Heinkel, who at the time was working for Albatros. It was taken into German service after the outbreak of war. It used the composite construction that would be the hallmark of Albatros aircraft. The fuselage had a wooden frame and was covered with plywood. The wings had wooden spars and ribs and were fabric covered. The radiators were mounted on the sides of the fuselage close to the front cockpit.
The B.I was then followed by the improved B.II, a two-bay biplane that led onto the armed C.I and a long family of Albatros scouts.
A floatplane version was developed as the Albatros W.I.
