Abstract: A motor vehicle door having a basic body (2; 22) and respectively an inside and an outside panel (4, 3; 23, 21; 27, 26), wherein the window-side circumferential edge (9) of the outside panel (3; 21; 26) is provided at least partially with an undercut (10) engaged by the corresponding regions of the circumferential edge of the basic body (2) or the inside panel (4), and wherein the outside panel (3) is provided with a folded section (16) at least at the end (15) of the circumferential edge (8) disposed opposite the window-side circumferential edge. To accomplish easy, quick and cost-advantageous mounting or replacement of the outside panel, the basic body (2; 22) or the inside panel (4; 23; 27) is connected by way of fastening means (18; 24; 28) to the wall region (20) of the folded section (14) of the outside panel (3; 21; 26), which wall region faces the door sill (14) of the corresponding motor vehicle.
