A steering holding determination device determines a steering holding state in which a driver of a vehicle holds a steering wheel of the vehicle in a steerable manner. The device includes a torque recognition unit that recognizes a steering torque based on a detection result of a torque sensor, a contact state recognition unit that recognizes a contact state or a non-contact state, a threshold value setting unit that sets a threshold value used for the steering holding state determination, based on a recognition result of the contact state recognition unit, and a steering holding determination unit that determines that the driver is in the steering holding state, when the steering torque is equal to or greater than the threshold value. When the non-contact state is recognized, the threshold value setting unit sets the threshold value to a larger value compared to a case when the contact state is recognized.
