A linear compressor includes a frame, an outer stator comprising a stator core disposed at the frame, a teeth portion extending inward from the stator core, and a teeth shoe extending in a circumferential direction from an inner end of the teeth portion, a coil disposed at the teeth portion, a cylinder disposed at the frame, a piston disposed in the cylinder, an inner stator coupled to an outer circumferential surface of the piston, a magnet is disposed at the teeth shoe, and a virtual pole that is disposed at the teeth shoe and faces the inner stator, the virtual pole being disposed at an axial front or an axial rear of the magnet. The outer stator includes a plurality of core plates stacked axially. A distance between the magnet and the inner stator is different from a distance between the virtual pole and the inner stator.
