Carnarvonia is a genus of arthropods of uncertain affinities, known from the Middle Cambrian Burgess Shale. It is only known from a single specimen, which preserves a dorsally flattened bivalved carapace, which bears the imprints of veins, and is superficially similar in shape to those of Phyllocarida and Canadaspis , the latter of which also occurs in the Burgess Shale.
