The '''Macchi M.12''' was a biplane flying boat bomber designed by Alessandro Tonini, and produced in small numbers by Macchi in Italy in 1918.<ref name="JEA">Taylor 1989, 617</ref>

==Design and development== The M.12 had a conventional design, generally similar to an enlarged version of other Macchi designs of the period, and featured the Warren truss-style interplane struts that had been introduced on the Macchi M.9.<ref name="JAWA 19 390">''Jane's All the World's Aircraft 1919'', 390</ref> A major difference however, was its twin-boom fuselage,<ref name="JEA" /> each with a separate tailfin.<ref name="JAWA 19 390" /> An M.12 was entered in the Schneider Trophy race of 1920, but did not compete.

The '''M.12''bis''''' was a civil variant with five seats and a wingspan extended to 18&nbsp;m (59&nbsp;ft), intended to carry passengers and mail.<ref name="JAWA 19 391">''Jane's All the World's Aircraft 1919'', 391</ref>
