A lane departure avoidance system includes: a recognition unit that recognizes a road edge of the road, and recognizes an outer line as a dividing line drawn on a road-edge side of a lane closest to the road edge; and an assist implementation unit that provides, within an area including the lane closest to the road edge and extending to the road edge, a forbidden position over which a vehicle is forbidden from going toward the road edge, and implements traveling assistance such that the vehicle does not go over the forbidden position. The system includes a shoulder width calculation unit that calculates, as a shoulder width, a width from the outer line to the road edge. The wider the shoulder width calculated by the shoulder width calculation unit is, the closer the forbidden position is set to the road edge by the assist implementation unit.
