PROBLEM TO BE SOLVED: To provide a steering control device mounted on a vehicle which is electrically steer-controlled capable of establishing the stabilization etc. of a body behavior when the vehicle turns. SOLUTION: A steering ECU 7 calculates a roll rate presumed value Rre on the basis of a steering angleδand lateral acceleration Gy fed from a lateral G sensor 16 at a step S4, and then at a step S5, sets a front-wheel side vehicle speed gain Kf and a rear-wheel side vehicle speed gain Kr on the basis of vehicle speed v using a map and/or a function. Then the steering ECU 7 calculates a front-wheel side steering correction value Sfc by multiplying the roll rate presumed value Rre by the front-wheel side vehicle speed gain Kf at a step S6, and then at a step S7, calculates a rear-wheel side steering correction value Src by multiplying the roll rate presumed value Rre by the rear-wheel side vehicle speed gain Kr.
