Tegopelte gigas (from the Greek tegos, "tile", and pelte, "leather-shield", referring to the shape of the dorsal body covering; gigas – from the Greek gigas, "giant", due to the huge size of the animal[1]) is a species of large soft-bodied arthropod known from two specimens found in the Middle Cambrian Burgess Shale of British Columbia, Canada.

The exopods (upper branch) of the limbs pairs bore elongated filament-like structures, and probably functioned as gills.

Trackways probably produced by Tegopelte are known from the Kicking Horse Shale, stratigraphically below its body fossil occurrences.

It is currently considered a member of the clade Conciliterga within Trilobitomorpha, a group which contains trilobites and their close relatives.
