An automotive lamp includes a first lamp unit, a second lamp unit, and a third lamp unit. The first lamp unit illuminates a first region PA1 having its longitudinal direction in the horizontal direction and having its upper edge defining a horizontal cutoff line CL1 in the low-beam mode and the high-beam mode. The second lamp unit illuminates a second region PB1 having its longitudinal direction in an oblique direction inclined with respect to the horizontal direction and having its upper edge defining an oblique cutoff line CL2 in the low-beam mode and the high-beam mode. The third lamp unit illuminates a third region PC1 having its longitudinal direction in an oblique direction inclined with respect to the horizontal direction and having its lower edge parallel to the oblique cutoff line CL2.
