Deanaspis is a genus of asaphid trilobites in the family Trinucleidae in the Ordovician periods. It is reported only from Northern Europe and Iran. It was named as a new genus in 1975.

In 2025, a member of the Galeaspida was given the same genus name ("Deanaspis" longpingi), with a replacement name yet to be chosen.
