Disclosed is a boil-off gas reliquefaction system. The boil-off gas reliquefaction system includes: a compressor compressing a boil-off gas; a heat exchanger cooling the boil-off gas compressed by the compressor by exchanging heat with the boil-off gas before being compressed as a refrigerant; a decompressing device installed in a back end of the heat exchanger and decompressing a fluid cooled by the heat exchanger; and a second oil filter installed in a back end of the decompressing device, wherein the compressor includes at least one oil-feeding cylinder and the second oil filter is for cryogenic temperature.
