The Renard R.30 was a prototype trimotor airliner built in Belgium in 1931.^[1] It was a strut-braced high-wing monoplane of conventional design with a fully enclosed flight deck and separate passenger compartment.^[2] One engine was mounted on the nose, while the other two were mounted on the leading edges of the wings.^[2] Construction was metal throughout, skinned in plywood and fabric.^[2]

The R.30 was designed in response to a Belgian government requirement of 1929 for a long-range passenger transport aircraft to service Belgian Congo.^[2] The design met the specifications laid down, but by the time it flew in 1931, it was judged already obsolete.^[2] The single prototype, registered OO-AMK, was the only example built.^[2]
