Wujicaris is an extinct genus of Early Cambrian crustaceans from the Maotianshan Shales of China.

Wujicaris is a crustacean known from the Chengjiang Lagerstatte, uniquely fossilised in Orsten-type preservation and known from four larval specimens in the early metanauplius stage roughly 270 μm long.

[2] Wujicaris possesses a large, pointed cephalic shield with an oval structure tentatively dubbed the "dorsal organ", a pair of possibly median eyes, an unsegmented body along with five pairs of appendages, three of those being mouthparts and the other two being antennae.

In addition, the labrum and hypostome are fused together, forming a large complex near the front of the organism.

The specific name, muelleri honours the late Klaus Müller, discoverer of Orsten-type preservation.
