Carpocoris fuscispinus is a species of shield bug in the family Pentatomidae.

Carpocoris fuscispinus can reach a length of 11–14 millimetres (0.43–0.55 in). The basic colour of the body is quite variable, ranging from greyish yellow to reddish brown, with tiny black dots. It has a sharp angled pronotum, most prominent in the summer than in autumn. Antennae are black.

Larvae are polyphagous, but they mainly occur on plants of the families Apiaceae and Asteraceae. Adults are commonly found from June to October. These shield bugs overwinter as adults.

This species is widespread throughout Europe. It mainly occurs in deciduous and mixed forest areas.
