The invention discloses a door with a ladder, and relates to the field of doors. The scheme is provided for the technical problem that the operation of getting up to and getting down from an attic through a traditional ladder is complex. The door comprises an upper door plate with one side connected to a door frame through hinges. A plurality of pedals are vertically arranged on the door plate at intervals. One end of each pedal is hinged to the door plate. Hinged hinge joints are provided with torsional springs so that the pedals can be attached to the door plate upwards. Limiting blocks used for limiting the amplitude of the pedals are fixed to the portions, below the pedals, of the door plate so that people can conveniently climb up and climb down the door of the attic.
