Anglaspis is an extinct genus of cyathaspidiform heterostracan agnathan. Fossils are found in marine strata of Europe, from the late Silurian period until the genus' extinction during the Early Devonian. As with other cyathaspidiforms, individuals of Anglaspis had dorsal and ventral plates covering the forebody, gill pouches, and nasal openings that lay on the roof of the oral cavity.{{Cite journal|last=Watson|first=David Meredith Seares|date=1954-10-28|title=A Consideration of Ostracoderms|journal=Phil.

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.{{Cite web|url=https://www.nhm.uio.no/besok-oss/utstillinger/tidligere%20faste%20utstillinger/fossiler/galleri/montre/english/118_554.htm|title=Anglaspis sp. - Naturhistorisk museum|website=Natural History Museum at the University of Oslo|language=no|access-date=2018-11-26}}{{cite journal |last1=Ilyes |first1=Robert R. |last2=Ohta |first2=Yoshihide |last3=Guddingsmo |first3=Jonny |year=1995 |title=The Downtonian and Devonian vertebrates of Spitsbergen. *.

Taxonomy
Anglaspis was, at various times, placed in the families Cyathaspididae,{{Cite journal|last1=Ilyes|first1=Robert R.|last2=Ohta|first2=Yoshihide|last3=Guddingsmo|first3=Jonny|date=1995-01-06|title=The Downtonian and Devonian vertebrates of Spitsbergen. *.

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.{{Cite journal|last1=Mette|first1=Lundgren|last2=Henning|first2=Blom|date=2011|title=Phylogenetic patterns in the heterostracan families Cyathaspidae, Ariaspidae and Ctenaspidae|url=http://uu.diva-portal.org/smash/record.jsf?faces-redirect=true&aq2=%5B%5B%5D%5D&af=%5B%5D&searchType=SIMPLE&query=&language=no&pid=diva2:476101&aq=%5B%5B%5D%5D&sf=all&aqe=%5B%5D&sortOrder=author_sort_asc&onlyFullText=false&noOfRows=50&dswid=-4721|journal=DIVA|pages=16–17}}
