Disclosed herein is an over-the-range oven including a body provided with a suction port and an exhaust port, an air blower unit causing air to be suctioned through the suction port and discharged through the exhaust port, and an air curtain unit movably installed at a lower portion of the body to generate an air curtain by discharging air. Since the air curtain unit is movable between a first position at which the air curtain unit is disposed close to the body and a second position at which the air curtain unit protrudes from the body, it may allow gas produced by a cooking apparatus disposed below the air curtain unit to be efficiently discharged.
