A vehicle steering control apparatus has a steering wheel, a steering mechanism mechanically separate from the steering wheel for steering the left and right front wheels and a reaction force motor for imparting an operation reaction force against the steering wheel. A steering motor is provided to impart a turning force to the steering mechanism, while a clutch is provided to mechanically connect and disconnect the steering wheel to and from the steering mechanism. A drive torque detector is provided to detect a drive torque imparted to the steering reaction force actuator. A torque sensor is provided to detect an operating torque imparted to the steering wheel. A clutch connection determiner determines that the clutch is in a connected state when a drive torque direction detected by the drive torque detector and an operating torque direction detected by the operating torque detector are different.
