An apparatus and a method are provided for learning a touch point of an engine clutch of a hybrid electric vehicle that learns the touch point of the engine clutch based on a change of an engine torque while the hybrid electric vehicle is running. The method includes determining whether an engine clutch coupling after shifting is required and whether a learning condition based on a running state of the hybrid electric vehicle is satisfied when the engine clutch coupling after shifting is required. A coupling pressure of the engine clutch is increased when the learning condition is satisfied and a changing amount of an engine torque based on the increased coupling pressure of the engine clutch is compared with a predetermined value. The touch point of the engine clutch is learned when the changing amount of the engine torque is greater than or equal to the predetermined value.
