A double prismantiprismoid is an isogonal polytope formed as the convex hull of two orthogonal prismantiprismoids and are generally nonuniform. They consist of alternating prisms and antiprisms in two orthogonal rings. The simplest non-trivial double antiprismoid is the digonal double prismantiprismoid, while the only uniform double prismantiprismoid is the rectified tesseract, considered as a transitional case of a digonal double prismantiprismoid. The dual of a double prismantiprismoid is a double tegmotrapezohedroid.

Double prismantiprismoids can vary in topology, even within the same base polygon and symmetry, such as the small triangular double prismantiprismoid and the great triangular double prismantiprismoid.
