To provide a vehicle behavior control device capable of more assuring a stabilization of a vehicle behavior.

First a yaw rate (r), a vehicle speed v, a body side slip angle β, and steering angles δf, δr, and θ are read (S10), and the tire side slip angles βf and βr of front and rear wheels are calculated (S102). Points (βf, βr) determined by tire side slip angles βf and βr on a prepared control map are retrieved (S103) so as to judge whether or not the points (βf, βr) are on the upper side of B line where a control yaw moment is not necessary (S104). When this judgment is YES, the symbol of the control yaw moment DYM is made positive (S105) and, when it is NO, the symbol of it is made negative (S106). Next, the determined control yaw moment DTM is fed to braking force control device (S107).
