The invention relates to a trailer coupling for a motor vehicle (400), comprising a coupling arm (11) for coupling a trailer (AHH) or a rear load carrier (HLL) and comprising a vehicle mounting (15) that is secured or can be secured to the motor vehicle (400) and has a bearing base (18) on which a coupling arm support (13) is pivotally mounted about at least one pivot axis (S) between a use position (G) and a non-use position (N) provided for when the trailer coupling (10) is not in use, said coupling arm support being equipped with the coupling arm (11) or a receiving body (312) for releasably receiving the coupling arm (11). The trailer coupling (10) has a fixing device (40) for fixing the coupling arm (11) in a stationary manner relative to the bearing base (18), and the coupling arm (11) can be moved between the use position (G) and the non-use position (N) relative to the bearing base (18) in a release position (L) of the fixing device (40) and is fixed in a stationary manner relative to the bearing base (18) in a fixing position (F) of the fixing device (40). The invention is characterized in that the fixing device (40) has a fixing actuation element (44), which can be adjusted between a fixing release position (FF) and a fixing actuation position (FB) along an actuation control movement (BS) on an actuation element guide (45a) of an actuation element guide body (45), in order to actuate at least one form-fitting element, which engages into a form-fitting receiving area in a form-fitting manner in the fixing actuation position (FB), such that the fixing device (40) assumes the fixing position (F), and which can be adjusted so as to be out of engagement with the form-fitting receiving area in the fixing release position (FF), such that the fixing device (40) assumes the release position (L); the trailer coupling (10) has a release drive which acts on a release drive contour (74) of the fixing actuation element (44) in order to actuate the fixing actuation element (44) in the direction of the fixing release position (FF); and the fixing actuation element (44) has a support element (75a, 75b) with a support contour (76) which is supported against a counter-bearing contour (86) of a counter-bearing element (80) while the fixing actuation element (44) assumes the fixing release position (FF).
