Hadranax is a genus of large lobopodian known from the lower Cambrian Sirius Passet Lagerstätte. This genus is characterized from other lobopodians due to multiple groups of four nodes running along its trunk region, similar to Kerygmachela, and a pair of extremely large frontal appendages that were possibly as long as the animal's entire body. This lobopodian is one of the rarer members of the Sirius Passet fauna, with only around three fragmentary specimens being known.
