The invention provides a wheel load estimation device and the like which can reduce the calculation load compared with the prior art when estimating the wheel load. According to one aspect of the present invention, there is provided a wheel load estimation device that estimates a wheel load applied to each wheel provided in a vehicle. The wheel load estimation device includes an acquisition unit, a calculation unit, and an estimation unit. The acquisition unit acquires a detection value output from the sensor as a parameter. The parameter is a parameter related to movement of the vehicle. The calculation unit calculates an inertia force generated in the vehicle on the basis of the parameter and the mass of the vehicle. The estimation unit estimates the wheel load on the basis of the inertia force and a predetermined estimation formula.
