Boreaspis (meaning "Boreas's Shield") is an extinct genus of osteostracan agnathan vertebrate that lived in the Devonian period.
Fourteen different species of Boreaspis have been found in sandstone of the lagoons and estuaries of Devonian Spitsbergen; however, some of these likely do not belong to the genus. The species B. robusta and B. costata have been reassigned to Spatulaspis; and B. circinus, B. curtirostris, and B. gracilis now belong to Dicranaspis.
