The Farman F.30 was a two-seat military biplane designed in France around 1915, which became a principal aircraft of the Imperial Russian Air Service during the First World War. Although it was widely used on the Eastern Front, and by the factions and governments that emerged in the subsequent Russian Civil War, it is not well-known outside that context: the F.30 was never adopted by other Allied air forces, and the manufacturers reused the "Farman 30" designation for an entirely different aircraft in 1917.

The F.30 was one of the final variants of the "Farman type", a distinctive aircraft layout developed by the Anglo-French brothers Henry and Maurice Farman. These were biplanes of a pusher configuration, with the propellor at the rear of the engine, behind the wings. The crew of two (pilot and observer) sat in front in an open cockpit, the wings were of a simple unstaggered) design, while the rear part of the plane was just a wire-braced framework supporting the tail.

The basic airframe of the F.30 was very similar to the earlier and slightly smaller F.20, a two-bay biplane with a shorter lower wing (a primitive sesquiplane layout), a reasonably long v-shaped tail framework, and similar control surfaces - ailerons on the outer sections of the upper wings, and a single rudder and a high tailplane at the rear. It differed by reviving the raised fuselage position of the 1913 MF.11, positioning the cockpit and engine half-way between the wings rather than mounting them directly on top of the lower wing, and it was the first Farman to adopt the simple and robust v-strut undercarriage that was becoming standard. Perhaps most importantly, it improved on the underpowered F.20 by utilizing the much more potent 150 hp Salmson 9 radial engine.
