A vehicle behavior information acquisition device includes: a neutral characteristic setting unit in which a vehicle velocity-neutral yaw rate characteristic where a behavior of a user's vehicle is supposed to be in a neutral state is previously set based on a vehicle velocity and a steering angle of the vehicle; and a behavior information acquisition unit for acquiring behavior information including an understeer state of the vehicle based on an actual yaw rate, a vehicle velocity, a steering angle, and a vehicle velocity-neutral yaw rate characteristic previously set in the neutral characteristic setting unit. The behavior information acquisition unit acquires behavior information indicating that the vehicle is in an understeer state in a case where a deviation between the actual yaw rate and a neutral yaw rate based on the vehicle velocity, the steering angle, and the vehicle velocity-neutral yaw rate characteristic exceeds a predetermined deviation threshold.
