Megachirella is an extinct genus of lepidosaur, possibly a stem-squamate that lived about 240 million years ago during the Middle Triassic and contains only one known species, Megachirella wachtleri. It is known from a partial skeleton discovered in the Dolomites of Northern Italy and was described in 2003.

==Description== left|thumb|Restoration of the skull in dorsal viewMegachirella is known exclusively from a partial skeleton, preserved in anatomical connection. The find includes an almost complete skull, the front half of the body and part of the front legs. The skull, although devoid of the front part of the snout, is rather robust and large; the neck is moderately elongated and the front legs are large and strong. The dimensions do not exceed in length, and the appearance is similar to that of a strong-legged lizard. ==Classification== left|thumb|Life restoration Megachirella was discovered in the Dont Formation of the area of Braies, in South Tyrol, and described in 2003. It was classified as a member of Lepidosauromorpha, the clade of reptiles that includes lizards, snakes, the tuatara and their closest extinct relatives, at the time. In particular, the fossils show some similarities, mainly in the skull, with some primitive forms such as the Eolacertilia. A phylogenetics analysis in 2013 confirmed that it was a lepidosauromorph closely related to the crown group Lepidosauria.
