Abstract: A portable canopy assembly for providing shade for outdoor events includes a mat that is foldable along pre-determined fold lines such that the mat forms a box. A plurality of stakes is each extendable through the mat at predetermined locations when the mat is folded to define the box. In this way each of the stakes penetrates a support surface for inhibiting the box from sliding on the support surface. A frame is provided and the frame is positionable between a collapsed position and a deployed position. The frame defines a half shell when the frame is positioned in the deployed position and the frame is positionable around the box when the mat is folded to define the box. A canopy is coupled to the frame such that the canopy extends partially over the box when the frame is positioned in the deployed for shading the box.
