The invention provides a foldable towel rack, and belongs to the field of bathroom tools. The problem that an existing towel rack is not applicable to a narrow toilet is solved. The foldable towel rack comprises two bases which are fixed to a wall, a vertical rotary shaft which is parallel to the wall is connected to the portion between the two bases, several shaft covers sleeve the rotary shaft,hinging parts are arranged on the outer walls of the shaft covers, rod-shaped towel rods are hinged to the hinging parts and are perpendicular to the rotary shaft, and can rotate around the axis of the rotary shaft, and hinging shafts of the hinging parts are perpendicular to the rotary shaft and the towel rods respectively, and can rotate around the hinging parts and turn the towel rods down. Bymeans of the foldable towel rack, on the basis of a towel rack of a traditional rotary structure, a foldable structure is further added to the towel rods, and once the walls at the two sides of the towel rack are occupied, multiple requirements can further be met through the foldable towel rods.
