An origami envelope and a method of constructing the origami envelope are enclosed. The origami envelope is quadrilateral in shape. The origami envelope comprises a top layer having a front surface and a back surface opposite to the front surface, and a bottom layer having an exterior side and an interior side opposite to the exterior side. The top layer extends to the exterior side of the bottom layer over a portion of the top envelope side to form a closure flap at the exterior side of the bottom layer.
