In a trailer coupling comprising a cross member unit, which is mountable on a tail region of a body and which extends transverse to a longitudinal direction of the vehicle body, in particular a passenger vehicle, and a bearing unit held by the cross member unit, by means of which bearing unit a ball neck with a coupling ball is held on the cross member unit, wherein the cross member unit is connected in its two outer, mutually opposed end regions to mounting elements by means of which the cross member unit is fixed to the tail region, in order to improve said trailer coupling in such a way that its mass is lower, whilst stability is unaffected, it is proposed that the cross member unit has an upper supporting structure as considered in the vertical direction and a lower supporting structure arranged lower down than the upper supporting structure in the vertical direction, that the supporting structures are each connected at their mutually opposed outer end regions to the mounting elements and in a central region carry the bearing unit, that one of the supporting structures is formed as a supporting structure that is primarily torsionally rigid and at least partially surrounds a structure interior, and that the other of the supporting structures is formed as a supporting structure that is primarily non-tensile in the direction of travel.
