The utility model relates to a sea wave power generation steamship, which can generate power with sea wave during - driving process of a steamship and comprises a steamship, wherein a sea wave water inlet communicated with a water pipeline is arranged at the front end of the steamship; a generator turbine is positioned in the water pipeline; and a turbine water outlet is located outside a cabin. The sea wave power generation steamship has the advantages that: on one hand, energy is provided for the steamship during the driving process, thus reducing consumption of the primary energy; on the other hand, emission of polluted gas is reduced while the energy consumption is reduced, thereby protecting environment.
