A method for learning engine clutch delivery torque of a hybrid vehicle includes: determining, by a controller, whether power transference of a transmission transmitting output from an engine of the vehicle and a motor of the vehicle is interrupted; controlling, by the controller, a speed of the motor to be maintained at a first speed when the power transference of the transmission is interrupted; calculating, by the controller, a first delivery torque of an engine clutch that connects the engine with the motor or disconnects the engine from the motor, based on the first speed and a second speed of the motor which is generated after the engine clutch is engaged; controlling, by the controller, the speed of the motor to be maintained at the second speed by releasing the engine clutch after the first delivery torque is calculated; and calculating, by the controller, a second delivery torque of the engine clutch based on the second speed and a third speed of the motor which is generated after the engine clutch is engaged.
