Alocodon (a-LOK-o-don; Greek alox and odon meaning 'furrow tooth') is a genus of ornithischian dinosaur from the Middle and Late Jurassic of what is now Portugal and also possibly England.[1][2] It was described in 1975 by Richard Anthony Thulborn. It had small ornithopod-like teeth with vertical grooves. This animal is only known from these teeth, and is usually considered a nomen dubium.

The type species is Alocodon kuehnei, the specific epithet honoring the German paleontologist Georg Kühne. The holotype is LPFU P X 2.

Though at first it was considered by Thulborn a member of the Fabrosauridae[3] and by Peter Galton a hypsilophodontid, Paul Sereno (1991) classified A. kuehnei as Ornithischia incertae sedis. Further studies indicate this species as a probable thyreophoran.[4]
