A linear compressor includes a mover which linearly reciprocates, a stator generating a driving force to allow the mover to linearly reciprocate and having a cylinder space formed on an inner circumferential surface thereof, a cylinder inserted into the cylinder space of the stator and having a compression space compressing a refrigerant, a piston reciprocating in an axial direction inside the cylinder, a frame provided on one side of the stator in an axial direction and supporting the stator in the axial direction, and a cylinder support member separated from the frame, provided between an inner circumferential surface of the stator and an outer circumferential surface of the cylinder, having one end fixed to the stator and the other end fixed to the cylinder, and supporting the cylinder with respect to the stator in the axial direction.
