The Monnett Moni is a sport aircraft developed in the United States in the early 1980s and marketed for homebuilding.

Designed by John Monnett, who coined the term "Air Recreation Vehicle" to describe it,^[1] it was a single-seat motorglider with a low, cantilever wing and a V-tail. Construction was of metal throughout, and it was intended to be easy and inexpensive to build and fly. Like many sailplanes, the main undercarriage was a single monowheel, which in this case was mounted in a streamlined fairing beneath the fuselage and was not retractable, with a steerable tailwheel behind it. Builders were also given the option of constructing their example with fixed tricycle undercarriage.^[2] Power was provided by a small two-cylinder, horizontally opposed, air-cooled engine.
