A door hinge has a first hinge plate connected with a second hinge plate that is adjustably disposed in a hinge accommodation element, so as to pivot, with a pin on a hinge roll. The hinge accommodation element has a front part and a rear part, and the second hinge plate is guided in the hinge accommodation element so as to move in the vertical direction, and can be tilted in the horizontal direction, relative to the hinge accommodation element, with an adjustment screw. The front part and the rear part of the hinge accommodation element are connected by a connection screw, and the second hinge plate is clamped in place between the front part and the rear part, so that it cannot be displaced in the vertical direction, after the connection screw has been tightened. A hinge system can be formed by three of these door hinges.
