The invention discloses a submarine cable torsional fatigue testing device, and relates to the technical field of torsional fatigue testing. Comprising a testing platform, a driving mechanism, a portal frame and a torque applying mechanism, the portal frame and the torque applying mechanism are fixed to the testing platform, the torque applying mechanism is located on the inner side of the portal frame, the fixed end of the driving mechanism is fixed to the testing platform, the output end of the driving mechanism is in transmission connection with the torque applying mechanism, and one end of a sample cable is fixed to the portal frame. And the other end is fixed on the torque applying mechanism. According to the invention, the cable can be vertically fixed, through the driving mechanism and the torque applying mechanism, the rapid and repeated application of the torsion load on the cable is realized, the cycle index of the torsion load is accurately controlled, the torsion accumulation phenomenon in the who
