Abstract: A secure package delivery assembly for preventing return or theft of a package includes a first bracket and a box. The first bracket is configured to couple to one of an upper end and a lower end of a door so that a first plate of the first bracket, to which the box is coupled, is positioned in substantial abutment to an exterior face of the door. An aperture that is positioned in a top of the box is configured to allow insertion of a package. A retention assembly that is coupled to and positioned in the box is configured to deter extraction of the package through the aperture. An opening is positioned in a horizontal face of the box to allow a user to retrieve the package. A panel that is hingedly coupled to the horizontal face is selectively couplable to the box to securely close the opening.
