The present invention provides a vehicle state estimating device, a vehicle control device, and a vehicle state estimating method. The vehicle state estimating device estimates the state amount of the vehicle at high accuracy from the wheel speed irrespective of the change in the vehicle property. The vehicle state estimating device includes a wheel speed detection unit that detects a wheel speed of each vehicle wheel; a vehicle speed detection unit that detects a vehicle speed; and a state amount estimation unit that estimates an unsprung state amount and/or a sprung state amount of the vehicle, based on a wheel speed of reverse phase of left and right wheels based on the wheel speed of each wheel detected by the wheel speed detection unit, and a value obtained by dividing a wheel base of a predetermined front-rear wheel by the vehicle speed detected by the vehicle speed detection unit.
