Burgessia is a genus of arthropod known from the mid-Cambrian aged Burgess Shale of British Columbia, Canada.

[1] The body had an unsegmented approximately circular carapace that was somewhat convex.

A pair of tapering flexible segmented antennae projected forwards from the head, which were about equal in length to the carapace, these were likely tactile in function.

There are three pairs of cephalic appendages excluding the antennae that functioned as walking limbs, as well as seven pairs of biramous walking limbs with gills, otherwise similar to the cephalic limbs running along the trunk, which decreased in size posteriorly.

Although not visible on any specimens, the mouth was almost certainly located on the underside of the body.
