Anglaspis is an extinct genus of cyathaspidiform heterostracan agnathan. Fossils are found in marine strata of Europe, from the late Silurian period until genus' extinction during the Early Devonian. Late Silurian species of Anglaspis are found in marine strata of Wales and England, while most of the Early Devonian species are found in the Devonian-aged strata of Spitsbergen island, in Svalbard, Norway.

Anglaspis was, at various times, placed in the families Cyathaspididae, Poraspididae, and in its own family, Anglaspididae. Currently, it is placed in Ariaspidae with Ariaspis, and Listraspis, and is considered to be closely related to, if not the progenitor of Liliaspis and Paraliliaspis.
