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

These segments had pronounced blade-like spines on their upper-outer edge.

The trunk terminated with a forked tailpiece, which on their outer edges had rod-like structures.

The two lobes were separated by a rectangular central piece.

It has been placed as a member of the family Jiangfengiidae, alongside Jianfengia, Sklerolibyon and possibly Parapeytoia.
