A linear compressor is provided in which a resonance frequency may be synchronized with an operating frequency. The linear compressor may include a fixed member including a cylinder, a movable member including a piston for compressing refrigerant in the cylinder, a center portion that coincides with the center of the piston, and a support that extends in a radial direction of the piston and linearly reciprocates about the fixed member, a plurality of front mainsprings arranged symmetrically about the center of the piston and each having one end supported on a front side of the support of the supporter and the other end supported on the fixed member, a single rear mainspring having one end supported on a rear side of the supporter and the other end supported on the fixed member, and a plurality of mass members coupled to a rear side of the supporter at a predetermined distance from the outer diameter of the rear mainspring.
