Anchipteraspididae is an extinct family of heterostracan vertebrates restricted to Late Silurian and Early Devonian strata of Arctic Canada.

Anchipteraspidids superficially resemble the ancestral cyathaspidids, but, the articulation and growth patterns of the plates clearly define them as pteraspidids.
