A laundry treating apparatus includes a cabinet including a rear plate that defines a rear surface of the cabinet, a drum rotatably disposed in the cabinet and configured to accommodate laundry, an air supply disposed in the cabinet and configured to dehumidify air discharged from the drum and to supply the dehumidified air to the drum, and a drain pipe configured to guide water that is condensed from the air discharged from the air by the air supply. The drain pipe passes through a first portion of the rear plate from an interior of the cabinet to an exterior of the cabinet, extends along a rear side of the rear plate at the exterior of the cabinet, and is inserted through a second portion of the rear plate from the exterior of the cabinet to the interior of the cabinet.
