Disclosed is an exhaust purification system for an internal combustion engine applied to a hybrid vehicle that performs EV travel after system power is turned on. The exhaust purification system includes: an exhaust purification catalyst; a heating element configured to generate heat with reception of power to heat the exhaust purification catalyst; a battery configured to supply the power to a motor and the heating element; a sensing unit configured to sense riding of an occupant in the hybrid vehicle; and a controller configured to execute first control to control the supply of the power from the battery to the heating element so that the power of electric energy of a prescribed ratio among activation electric energy is supplied to the heating element when the riding of the occupant is sensed by the sensing unit and a storage amount of the battery is larger than a second storage amount.
