A residual voltage controller and an electric compressor including the same, which aim to prevent an electric shock or an accident caused by detachment of a high voltage connector through safe interruption of a residual voltage using a plurality of switching elements. The residual voltage controller includes a high voltage connector having an interlock, an inverter part configured to receive power from the high voltage connector, a motor part electrically connected to the inverter part to be controlled, and voltage controllers connected between the high voltage connector and the inverter part in each different direction to interrupt a residual voltage of the motor part when detachment of the high voltage connector is performed before a normal stop signal.
