Lepagia is an extinct genus of poorly known carnivorous cynodonts, which lived during the Upper Triassic in Europe.

The genus Lepagia ("for Lepage") was named by Hahn, Wild and Wouters in 1987 based on a single species.

Fossil remains of the species Lepagia gaumensis have been found in the Norian (late) - Rhaetian (early) (Upper Triassic)-age strata from Habay-la-Vielle, Hallau, Saint-Nicolas-de-Port in Belgium, Switzerland and France.

The postcanines have long and narrow crowns with three to five cusps, the central one of which is dominant and points straight upwards.

Godefroit and Battail cite similarities and differences with and to both Chiniquodontidae and Dromatheriidae and leave the systematical placement open.
