A vehicle steering assist device includes a steering assist ECU. The steering assist ECU calculates a target steering angle for driving the vehicle along the road, and a target steering guide torque that guides the driver's steering so that the actual steering angle becomes the target steering angle. The steering assist ECU controls the torque applying device so that the steering guide torque becomes the target steering guide torque. The steering assist ECU acquires at least one of information on the driving environment of the vehicle and information on the state of the driver, and calculates an index value indicating the necessity of the steering guide torque based on at least one of the pieces of information. The steering assist ECU corrects the target steering guide torque based on the index value so that the higher the need for the steering guide torque, the larger the target steering guide torque.
