Armadillidium pulchellum is a species of woodlice belonging to the family Armadillidiidae.

[1] It only grows to approximately 5 millimetres (0.20 in) in length.

It is spotted with yellow dots and often red-brown at the edge of its pereonites.

It has a wide telson, which is roundly truncated.

Its volvation is not perfect, meaning it leaves a small gap when it rolls up.
