Arctolepis is an extinct genus of placoderm arthrodire fish which lived during the Early Devonian period (408 – 307 million years ago). Fossils of Arctolepis have been found in what is now Norway and Michigan.

Classification

Within Arthrodira, Arctolepis is considered a member of "Phylctaenii", a paraphyletic grouping within the clade Phlyctaenioidei, basal to the suborder Brachythoraci. Arctolepis is most closely related to Heintzosteus and Dicksonosteus.

Arctolepis contains the following six species:

• †Arctolepis brevis Heintz, 1929
• †Arctolepis decipiens Woodward, 1891
• †Arctolepis lata Heintz, 1929
• †Arctolepis lewini Heintz, 1929
• †Arctolepis longicornis Heintz, 1929
• †Arctolepis solnoerdali Heintz, 1929
