A suspension device includes an actuator capable of generating a thrust force and a controller. The controller includes a first vibration suppression force computation unit configured to obtain a first vibration suppression force from a vertical velocity of a sprung member, a second vibration suppression force computation unit configured to obtain a second vibration suppression force from a vertical velocity of the unsprung member or a relative velocity between the sprung member and the unsprung member, a low-pass filter having a breakpoint frequency between a sprung resonance frequency and an unsprung resonance frequency and processing a signal in the course of obtaining the second vibration suppression force using the second vibration suppression force computation unit, and a target thrust force computation unit configured to obtain a target thrust force of the actuator on the basis of the first vibration suppression force and the second vibration suppression force.
