A linear compressor (100) comprises: a stationary member including a cylinder (200) for providing a space for compressing a refrigerant; a movable member linearly reciprocating with respect to the stationary member, and including a piston (300) for compressing the refrigerant inside the cylinder (200) and a supporter piston (320) having a support portion extended in a radial direction of the piston (300); a plurality of front main springs (820) positioned so as to be symmetrical with the center of the piston (300) and the supporter piston (320), one ends of which being supported by the front surface of the support portion of the supporter piston (320) and the other ends of which being supported by the stationary member; one rear main spring (840), one end of which being supported by the back surface of the supporter piston (320); a suction muffler (700) providing a passage for introducing a refrigerant while reciprocating with the movable member, reducing noise, and including an extended part extended toward the supporter piston (320); and a spring guide fixed to the supporter piston (320) to support one end of the rear main spring (840) on the front surface, a recessed part having a size enough to accommodate the extended part of the suction muffler (700) being formed on the back surface of the spring guide (900).
