A trailer coupling for a motor vehicle comprises a coupling arm, on the free end region of which a ball neck is formed, on which a coupling ball is arranged. The coupling ball is spherical on the side facing away from the ball neck and has a spherical segment plane on the side facing the ball neck. Between the spherical segment plane and a portion of the ball neck has a smaller outer circumference than the spherical segment plane there is arranged a throat portion having a transition contour extending in a concave manner between the ball neck and the spherical segment. The transition contour transitions with a coupling ball transition region into an external contour of the coupling ball and transitions with a ball neck transition region into an outer surface of the ball neck. The transition contour has a curved configuration having a non-constant radius.
