The invention relates to a motor vehicle door, consisting of an interior sheet metal and an exterior sheeting, together which form a hollow interior space of the door, having an opening in the interior sheet metal and having a carrier module that closes said opening, and carries at least one functional part of the motor vehicle door, such as a hinge part, lock part or window lifter part. In order to simplify the assembly of a motor vehicle door it is proposed that the vehicle door (10) features, apart from the opening (18) in the interior sheet metal (12) which may be closed by means of a carrier module, an additional access opening (22) adequately large for inserting the carrier module, including the at least one functional part, into the interior space (16) of the door and that the carrier module consists of a base plate (20) which closes the opening (18) of the interior sheet metal (12) from the side of the hollow interior space (16) of the door.
