Fukuiraptor ("thief of Fukui") was a medium-sized carnivore of the Early Cretaceous (Barremian) that lived in what is now Japan. Scientists first thought it was a member of the Dromaeosauridae, but after studying the fossils they then believed it was related to Allosaurus (which is classed in a different family) in the family Neovenatoridae. However, more recently, another analysis has proposed that all megaraptorans are actually tyrannosauroids, which would reclassify Fukuiraptor as a tyrannosauroid coelurosaur. Recent cladistic analysis of the theropod Gualicho has suggested that Fukuiraptor and other megaraptorans are either allosauroids, or non-tyrannosauroid basal coelurosaurs.
