Officine Ferroviarie Meridionali or OFM was an Italian railway and rolling stock manufacturing company based at Naples.

Nicola Romeo following closely the success of Fiat, he considered that the OFM Naples factory and its workforce was suitable to be trained in order to produce aircraft parts and even a plane.

While this quickly became one of the world's most famous automakers, the collapse of Banca Italiana di Sconto led Romeo to reacquire OFM.

[1] Obsessed with his aviation factory dream, Nicola Romeo hired Alessandro Tonini as OFM's chief designer.

The aircraft produced in Napoli by OFM from 1925 onwards frequently carried the inscription Aeroplani Romeo painted somewhere on the airframe.
