A driver support device includes: a drive device configured to change a steering angle being an angle of a steered wheel of a vehicle by applying torque to a steering shaft coupled to a steering wheel of the vehicle; and a control unit. The control unit executes lane departure avoidance control controlling the drive device to change the steering angle to avoid departure of the vehicle from a traveling lane when a start condition is satisfied, and is configured to execute the lane departure avoidance control such that, when a holding position of the steering wheel by a driver does not meet a predetermined specific condition upon satisfaction of the start condition, a magnitude of a steering angular velocity being an amount of change in the steering angle per unit time is smaller than the magnitude when the holding position meets the specific condition upon satisfaction of the start condition.
