    The present invention is to provide a methanol fuel propulsion ship that can reduce the emissions of sulfur oxides and carbon dioxide in exhaust gas by using methanol as fuel. According to one aspect of the present invention, a ship including a methanol fuel supply system may comprise: a low-pressure fuel supply line which delivers methanol from a methanol storage unit to a low-pressure demand; a 1-1 pump provided in the low-pressure fuel supply line to primarily pressurize methanol; a heat exchanger provided at a rear end of a first pump to heat methanol; a 1-2 pump provided at a rear end of the heat exchanger to secondarily pressurize methanol; a first return line branched downstream of the 1-2 pump and returning methanol to the upstream of the heat exchanger; a second return line branched downstream of the heat exchanger and returned upstream of the 1-1 pump; and a high-pressure fuel supply line branching downstream from the heat exchanger and delivering methanol to a high-pressure demand.
