Abstract: A linear compressor and a refrigerator including a linear compressor are provided. The linear compressor may include a shell coupled to a suction inlet, through which a refrigerant may be introduced, and a discharge outlet, through which the refrigerant may be discharged, a cylinder disposed within the shell to accommodate a piston reciprocated to compress the refrigerant introduced through the suction inlet, a frame that accommodates the cylinder, the frame being mounted inside the shell, and a discharge cover coupled to a front surface of the frame to discharge the refrigerant compressed by the piston to the discharge outlet. A front surface of the cylinder that faces the discharge cover may be spaced a predetermined distance from the discharged cover.
