A linear compressor includes a cylinder that defines a compression space for a refrigerant, a frame that fixes the cylinder to a shell, a piston that axially reciprocates in an interior of the cylinder, a discharge valve that is provided in front of the cylinder to selectively discharge the refrigerator compressed in the compression space for the refrigerant, a discharge cover that is coupled to the frame and has a discharge space for the refrigerant discharged through the discharge valve, a valve spring that provides an axial resilient force to the discharge valve while supporting the discharge valve, and a valve support device that is coupled to the valve spring and supported by the frame to deliver vibration generated by the discharge valve to the frame.
