The invention discloses a cup lid with a telescopic suction tube and a water cup and belongs to the field of articles for daily use. An upper lid and a lower lid are connected to form a cavity, a spring coiling mechanism and a rotary table capable of rotating relative to the cavity are arranged in the cavity, the spring coiling mechanism is located at the inner top of the upper lid and/or the inner bottom of the lower lid, the center of the lower end face of the rotary table and/or the center of the upper end face are provided with protrusions extending into the spring coiling mechanism to be matched with a spline, the protrusion at the center of the lower end face of the rotary table is tubular and penetrates though the lower lid. A hose is wound on the rotary table, one end of the hose is communicated with the tubular protrusion of the lower end face of the rotary table, and the other end of the hose penetrates through a side wall of the upper lid to be connected to a water nozzle pulling-on piece which can be far away from or be adhered to an outer side wall of the upper lid. By means of the cup lid and the water cup, patients lying in beds, drivers driving vehicles and other people who are in a nonstatic state or in a non-normall state can safely, effectively, conveniently drink water and beverage by themselves.
