The utility model provides a piston cooling nozzle, and belongs to the technical field of engine parts. The problem that the service life is short due to the fact that a spring in an existing cooling nozzle is excessively extruded easily is solved. The piston cooling nozzle comprises a connector bolt provided with an oil inlet hole and a communicating hole, a nozzle body arranged on the connector bolt in a sleeving mode and a fixing cap fixedly connected to the connector bolt, a spring and a valve ball used for blocking the oil inlet hole under the action of the spring are arranged in the connector bolt, and the piston cooling nozzle is characterized in that a mounting cylinder is arranged at one end of the fixing cap; one end of the spring extends into the inner cavity of the mounting cylinder and abuts against the fixing cap, a limiting base capable of abutting against the position between the valve ball and the mounting cylinder is inserted into the other end of the spring, and the limiting base is in clea
