Asteracanthus (from , 'star' and , 'spine') is an extinct genus of hybodont, known from the Middle Jurassic (Bathonian) to the Early Cretaceous (Valanginian).
== Description == left|thumb|Dentition of Asteracanthus ornatissimus Asteracanthus was among the largest known hybodontiforms, reaching a length of . The dentition of Astercanthus is high crowned and multicusped. The low-rounded teeth previously attributed to the genus actually belong to Strophodus.
