Orconectes inermis, the Northern cave crayfish, is a troglomorphic freshwater crayfish native to Kentucky and Indiana in the United States.[1][2]

There are two sub-species described;

• Orconectes inermis inermis, known as ghost grayfish
• Orconectes inermis testii (Hay, 1891), known as unarmed crayfish

The two sub-species are known to form intergrades in the range where they overlap.[2]
