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