Sklerolibyon is an extinct genus of megacheiran arthropod, known from the Cambrian aged Chengjiang biota of Yunnan, China.

It is a member of the family Jianfengiidae, alongside Jianfengia and Fortiforceps, and possibly also Parapeytoia.

The body is greatly elongated, and head shield is heavily sclerotised, with a pair of spines radiating outward from the sides.

The trunk has 34 segments with corresponding biramous appendages, with typically megacheiran paddle-shaped exopods.

The tail is unknown but like Jianfengia probably ended in a telson spine.
