The present invention relates to a gas treatment system and a ship including the same, The gas treatment system provided in a ship propelled by using liquefied gas as a fuel comprises: a fuel tank for storing liquefied gas; a liquefied gas supply unit for supplying the liquefied gas of the fuel tank to a propulsion engine that propels the ship; and a boil-off gas supply unit for supplying boil-off gas generated in the fuel tank to the power generation engine, wherein the boil-off gas supply unit includes a compressor that compresses the boil-off gas of the fuel tank and supplies the same to the power generation engine, and the compressor is provided to have a maximum discharge pressure lower than a design pressure of the power generation engine. In order to treat boil-off gas generated from the fuel tank, the boil-off gas is supplied to the power generation engine, but the compressor specifications can be lowered by setting the compressor discharge pressure below the power generation engine design pressure.
