Dubreuillosaurus is a genus of carnivorous megalosaurid theropod dinosaur from the middle Jurassic Period. Its fossils were found in France. The only named species, Dubreuillosaurus valesdunensis, was originally described as a species of Poekilopleuron, Poekilopleuron? valesdunensis, which is still formally the type species of the genus. It was later renamed Dubreuillosaurus valesdunensis when, in 2005, Allain came to the conclusion that it was not part of the genus Poekilopleuron. Its type specimen, MNHN 1998-13, is only rivalled in the number of preserved elements in this group by that of Eustreptospondylus. Dubreuillosaurus is considered to be a sister taxon of Magnosaurus. It did not show signs of insular dwarfism even though it was uncovered on an island.
