Lebachacanthus is a genus of extinct xenacanth cartilaginous fish known from the late Carboniferous-Early Permian of Europe. Well-preserved specimens, originally identified as Orthacanthus, are known from Meisenheim Formation in Germany. During the late Paleozoic, xenacanths were the apex predators of freshwater ecosystems, preying on small amphibians.
