To provide a vehicle steering control device effectively suppressing upward movement of a vehicle body in rolling of the vehicle body without degrading the ride quality.

The vehicle steering control device comprises: right, left, front, and rear wheels FL, FR, RL and RR supported in the vehicle body by a suspension mechanism 2; all-wheel independent steering control means 3 and 4 capable of independently controlling steering angles of the right, left, front, and rear wheels FL, FR, RL and RR; and a roll detecting means 5 for detecting a roll state of the vehicle body. When the vehicle body is detected to roll by a roll detecting means 5, the all-wheel independent steering control means 3 and 4 toe out at least either the right and left front wheels FL and FR or the right and left rear wheels RL and RR.
