Stanleycaris ("Stanley's shrimp") is an extinct genus of hurdiid radiodont from the Cambrian (Stage 3 to Miaolingian). The type species is Stanleycaris hirpex. Stanleycaris was described from the Stephen Formation near the Stanley Glacier and Burgess Shale locality of Canada, as well as Wheeler Formation of United States.
