A variable valve system for an internal combustion engine includes a plurality of engine valves provided per one cylinder; a swing arm configured to perform an opening-and-closing operation of at least one of the plurality of engine valves by swinging about a fulcrum given by a support member; a variable lift mechanism configured to cause the swing arm to swing, and to vary a lift amount of the at least one of the plurality of engine valves; a valve stop mechanism provided for the at least one of the plurality of engine valves and configured to stop the opening-and-closing operation of the at least one of the plurality of engine valves by producing a lost motion of the support member; and an engine-speed limiting section configured to variably limit a maximum rotational speed of the internal combustion engine in accordance with a displacement amount of the lost motion.
