The invention discloses a telescopic accommodation ladder which comprises an upper platform, an upper ladder portion, a middle ladder portion, a lower ladder portion, an oil cylinder, a winch, a stand column, a suspension arm and a steel rope. The upper platform is installed on a ship side deck. The winch and the suspension arm are sequentially installed on one side of the upper platform in a spaced mode. The back of the suspension arm abuts against the stand column. The steel rope pulled by the winch is driven by the stand column and the suspension arm to drag the upper ladder portion. The upper end of the upper ladder portion is hinged to the upper platform. The upper ladder portion is internally provided with the middle ladder portion and the lower ladder portion which are axially sleeved. The oil cylinder is coaxially installed on the bottom face of the upper ladder portion. The oil cylinder is internally provided with two sections of sleeved piston rods, wherein the end of the piston rod with the smaller diameter is connected with the free end of the lower ladder portion to form a structure that the lower ladder portion and the middle ladder portion are controlled by the oil cylinder to be axially telescopic relative to the upper ladder portion. The three-section sleeved accommodation ladder is simple and compact in structure, the length size is small during retraction, storage is convenient, and the accommodation ladder is particularly suitable for being matched with a ship with the small ship side deck space.
