A rotational speed control apparatus for an engine that drives an air conditioning compressor includes an electronic control unit. The electronic control unit corrects a calculated value of a load torque of a compressor in accordance with a deviation between a rotational speed of the engine and a target rotational speed, as a changeover transition period control, in a changeover transition period. The electronic control unit also sets an execution period of the changeover transition period control such that the execution period in a changeover transition period from the stopped state to the driven state of the compressor is longer than an execution period of the changeover transition period control in a changeover transition period from the driven state to the stopped state of the compressor.
