The invention discloses a hydraulic spud lifter. The hydraulic spud lifter comprises an upper ring beam and a lower ring beam which are connected to a spud, a hoister cylinder is arranged between the upper and lower ring beam, and the hoist cylinder are connected to the upper and lower ring beams through cylinder hinge shafts, and a latch cooperate with a latch hole in the spud. The lower ring beam is connected with a hinge seat firmly welded to a deck via a hinge. Self lubricating joint bearings are mounted in upper and lower hinging points of a hinge, so that the hinge can swing to compensate unbalance caused by the inclined spud or deformation of a hull. A latch on the lower ring beam is a support latch, a latch on the upper ring beam is a work latch, at least on latch of the upper or lower ring beams is in a latch hole when the hydraulic spud lifter works, so as to ensure the safety. The hydraulic spud lifter is reasonable in structure and good in work performance. The latches of the upper and lower ring beams are inserted in the latch hole in the spud by turns, the spud can be lifted or put down by telescoping a piston of a hydrocylinder, so the hull can be lifted and put down at the same time.
