The embodiment of the invention discloses an invisible folding ladder for a ship. The folding ladder comprises a ladder frame 1, a plurality of steps 2, a handrail pipe 3, a handrail supporting rod 4, a push rod 5 and a hand-cranking screw folding and unfolding device 6, a plurality of steps 2 are equidistantly hinged on the ladder frame 1; the armrest tube 3 is hinged with the armrest supporting rod 4; the handrail supporting rods 4 are fixedly connected with the multiple steps 2 at intervals of more than two steps, and the handrail supporting rods 4 and the multiple steps 2 are jointly hinged to the ladder frame 1; the push rod 5 is hinged with a rear connecting rod of the multi-stage step 2; the upper portion of the hand-cranking screw retracting and releasing device 6 is hinged to the lower portion of the push rod 5, and the lower portion is hinged to a base welded to a deck. The folding and unfolding structure can be changed into two different forms through folding and unfolding, and the stealth requirement and the passing convenience and safety requirements are met at the same time.
