Naraoiidae is a family, of extinct, soft-shelled trilobite-like arthropods, that belongs to the order Nektaspida.

Species included in the Naraoiidae are known from the second half of the Lower Cambrian to the end of the Upper Silurian.

This is probably due to the rare occurrence of the right circumstances for soft tissue preservation, needed for these non-calcified exoskeletons.

Naraoiids probably were deposit feeders (Naraoia and Pseudonaraoia), predators or scavengers (Misszhouia), living on the sea floor.

The taxonomic placement of the Naraoiidae has long been debated until detailed appendages were uncovered, that showed that N. compacta shares biramous legs of very comparable anatomy with trilobites.
