The disclosure relates to a motor vehicle door lock, having a locking mechanism that includes a rotary latch and at least one pawl. A drive for acting on the locking mechanism is also provided. A blocking element which interacts with the pawl has at least one pawl arm which holds the pawl in a latching position. Finally, a stop arm is realized on the blocking element and/or on the pawl and/or on a release element, the stop arm acting as a stop for the drive. The blocking element is arranged on an edge which is averted from the rotary latch and also so as to laterally overlap the pawl.
