An apparatus and a method for controlling an engine stop of a hybrid electric vehicle are provided to charge the vehicle by advancing control completion time for the engine stop and using inertial energy of the engine. The method includes determining a sensing speed for executing the engine stop when required and determining a value of control timeout based on the sensing speed. A torque is applied to an HSG based on the sensing speed and the value of control timeout is compared with a counter value when the sensing speed is equal to or greater than a predetermined speed. The counter value is increased when the counter value is equal to or less than the value of control timeout. The sensing speed is redetermined, the torque application to the HSG is stopped and the counter value is reset when the counter value is greater than the control timeout value.
