A refrigerator includes a cabinet that defines a storage space and a machine compartment that accommodates a compressor, a blow fan, and a condenser. The condenser is curved along front, rear, and side surfaces of the machine compartment. The condenser includes a first header disposed at a first end of the condenser, a second header disposed at a second end of the condenser, tubes that connect the first header and the second header to each other, an input connection portion that extends from the first header toward the second header and is configured to supply refrigerant to the first header, and an output connection portion that extends from the first header toward the second header and is spaced apart from the input connection portion. The output connection portion is configured to receive the refrigerant discharged from the first header.
