Disclosed is a boil-off gas reliquefaction system for a ship. According to the present invention, the boil-off gas reliquefaction system for a ship can comprise: a compression unit including a first compressor receiving and compressing boil-off gas generated from liquefied gas of a cargo tank arranged in the ship, and a second compressor additionally compressing the boil-off gas compressed in the first compressor, and compressing the boil-off gas in multiple stages; an intercooler receiving the boil-off gas compressed in the first compressor, and cooling the boil-off gas, and supplying the boil-off gas to the second compressor; a condenser cooling the boil-off gas compressed through the compression unit; a reliquefaction gas recollection line recollecting chill from the reliquefied gas cooled and condensed in the condenser through the intercooler, and transporting the liquefied gas to the cargo tank; and a first temperature control line branching the liquefied gas in the reliquefaction gas recollection line, and injecting the liquefied gas to the upper side of the intercooler. Therefore, the reliquefaction rate can be increased.
