The Morelli M-100 was a single-seat sailplane designed in response to a 1956 competition sponsored by the Aero Club d'Italia for a low-cost training glider.

As originally designed, the M-100 was of conventional, high-wing sailplane configuration, with a stubby T-tail.

In 1958, the FAI published the new Standard Class rules for sailplanes, and since the M-100 was close to this specification, the design was modified to comply.
