PROBLEM TO BE SOLVED: To provide an intake control apparatus for an internal combustion engine with superior high speed following performance when varying an intake introducing time period by opening and closing a plurality of intake control valves. SOLUTION: The intake control apparatus of an internal combustion engine includes: respective intake valves 5 opened when intake air reaching respective branch intake paths r1 from a main intake path Rim of the internal combustion engine is introduced to respective combustion chambers 2; respective intake control valves 15 respectively arranged upstream from the intake valves on the respective branch intake paths; an opening and closing drive means 16 for individually opening and closing each of the intake control valves; and a phase varying drive means 25 for displacing a phase of opening and closing timing of each intake valve. Driving of the opening and closing drive means 16, and driving of the phase varying drive means 25 are controlled by a control means 17 to adjust the intake introducing time period Tq for carrying out respective introduction into a combustion chamber 2.
