A linear compressor (10) includes a shell (100) in which a refrigerant suction part (101) is disposed. A cylinder (120) is provided inside the shell. A piston (130) reciprocates inside the cylinder. A motor assembly (200) provides a driving force for movement of the piston. A magnet assembly (300) delivers the driving force exerted by the motor assembly to the piston. The magnet assembly (300) includes a magnet frame (310) having a cylinder shape. A permanent magnet (350) is installed in the magnet frame. A coupling plate (330) is coupled one side of the magnet frame and includes a flange part (335) coupled to an end portion of the permanent magnet.
