An apparatus and a method for controlling an engine clutch of a hybrid electric vehicle control a torque of an input shaft of the engine clutch to 0 by using an integrated hybrid starter and generator (HSG) and releases the engine clutch. The method may include: determining whether a release of the engine clutch is required while the hybrid electric vehicle is operating with fuel cut off; calculating an engine friction torque; increasing an output torque of the HSG by an absolute value of the calculated engine friction torque; decreasing a motor torque corresponding to the output torque of the HSG; and releasing the engine clutch when the output torque of the HSG is equal to the engine friction torque.
