In a hybrid electric vehicle and a touchpoint learning method therefor, while a motor is driven, an engagement oil pressure of an engine clutch is adjusted step-by-step, to learn a touchpoint, thereby reducing touchpoint learning time and improving learning accuracy. The touchpoint learning method may include: determining whether a touchpoint learning entry condition previously set is satisfied or not; controlling a first motor connected to one end of an engine clutch to be in a stopped state when the learning entry condition is satisfied; maintaining a second motor connected to the other end of the engine clutch at a preset speed; changing an engagement oil pressure of the engine clutch step-by-step; and learning a touchpoint of the engine clutch based on a torque change of the second motor.
