"Kuehneodon" is a genus of extinct mammal of the Upper Jurassic - Lower Cretaceous of Europe. It was a relatively early member of the also extinct order of Multituberculata. Members of this genus lived alongside such dinosaurs as Allosaurus. It belongs to the suborder "Plagiaulacida", family Paulchoffatiidae. In addition, this genus is presently the only known member of a subfamily called Kuehneodontinae. It was named by Hahn G. in 1969, the name meaning "Kühne’s tooth" in honor of paleontologist Walther Kühne, pioneer of the Guimarota site of Portugal where remains were found in the late [1950] s and early 1960s.

"Kuehneodon" is the one genus of the taxon Paulchoffatiidae from the Guimarota site whereby the lower and upper jaws have been found united. These "exhibit the lowest number of derived characters (apomorphies), and are thus closest to the main evolutionary lineage of the multituberculates" (Hahn & Hahn 2000, p.106).

The genus is based mainly upon remains of jaw, a number of species are recorded from Guimarota: "Kuehneodon dietrichi" Hahn G, 1969; "K. dryas" Hahn G, 1977; "K. guimarotensis" Hahn G, 1969; "K. simpsoni" Hahn, 1969 and "K. uniradiculatus" Hahn, 1978. A further Upper Jurassic, Portuguese locality near Lourinhã, Porto das Barcas, has yielded "K. barcasensis" Hahn G & Hahn R, 2001. Lower Cretaceous fossils have also been found in Galve, Spain.K. hahni Antunes, 1998 was reported from Paimogo, Lourinhã, by Miguel Telles Antunes.
