The invention relates to a LNG gas ventilation mast for a ro-ro passenger ship, which comprises a barrel, a first ventilation pipe and a second ventilation pipe, and the barrel inclines towards the stern direction and is fixedly installed on an exposed deck and provided with a first channel and a second channel which are spaced from each other and extend in the length direction. The top of the first channel and the top of the second channel are provided with a ventilation net and a rainproof cover, the first channel is divided into a plurality of cavities which are separated from one another, the size of the cavities is in positive correlation with the caliber of the first ventilation pipe, the caliber of the second ventilation pipe is smaller than that of the first ventilation pipe, and the diameter of the second ventilation pipe is smaller than that of the second ventilation pipe. The first vent pipe penetrates out of the exposed deck and then extends by a preset length in the cavity, and the second vent pipe penetrates out of the exposed deck and then extends to the top in the second channel. The internal structure is reasonably divided, the structure is compact, the occupied space is small, and functionality and attractiveness are both considered.
