Abstract: A linear compressor is provided. The linear compressor may include a cylinder that defines a compression space, a piston having a plurality of suction holes through which a refrigerant is introduced into the compression space, and a muffler connected to the piston and through which the refrigerant supplied to the piston flows. The muffler may include a seat seated on one side of the piston, and a protrusion arranged inside the piston. The protrusion may include plurality of flow pipes that extends from the seat to an inside of the piston to guide the refrigerant to the plurality of suction holes and a resonator arranged at one side of the plurality of flow pipes and having a resonance space therein.
