A rotational speed control apparatus for an engine is provided. The engine is configured to drive a compressor for air conditioning. The rotational speed control apparatus includes an electronic control unit. The electronic control unit is configured to: (a) correct a calculated value of the load torque in accordance with a deviation between a rotational speed of the engine and the target rotational speed, as changeover transition period control, in a changeover transition period; and (b) set an execution period of the changeover transition period control such that the execution period in a changeover transition period from the stopped state of the compressor to the driven state of the compressor becomes longer than an execution period of the changeover transition period control in a changeover transition period from the driven state of the compressor to the stopped state of the compressor.
