In a vehicle door hinge, a moving hinge member is fixed to a mounting surface of a door, and a fixed hinge member is fixed to a mounting surface of a vehicle body. The moving hinge member is pivotally mounted to the fixed hinge member via a hinge shaft. The fixed hinge member has a deformation-promoting portion which meets the mounting surface of the vehicle body at an intersection. An extension line extends from a facing side of the fixed hinge member facing the mounting surface of the door. First and second tangential lines which contact an outer circumference of the hinge shaft extend perpendicular the mounting surface of the vehicle body. The intersection is positioned between the extension line and the second tangential line remote from the extension line compared with the first tangential line. The facing side is formed at right angles or approximate right angles with respect to the mounting surface of the vehicle body, and the fixed hinge member is unfolded to a T-shape.
