The invention provides a stem wave elimination device, which comprises a pipeline arranged in the stem and a propeller arranged in the pipeline. The device of the invention can efficiently reduce wave resistance, frictional resistance and differential pressure resistance. An impeller can generate electricity by utilizing the tail flow of the propeller so as to save energy. The device can improve a finished ship and has a function of reducing the wave-making resistance, frictional resistance and sticky pressure resistance.
