A portable, inflatable canopy is disclosed having an inflatable support system including interconnected, intersecting arches over which a tarp is secured to form a dome structure that can be temporarily anchored to the ground as a respite for sun, heat, wind, and rain. The inflatable support system works with a battery powered fan to inflate the canopy quickly without outside power requirements, and the fan can also be used to quickly deflate the canopy. The use of all soft materials allows the canopy to be folded or rolled when deflated into a compact storage configuration without poles, rigid supports, or other cumbersome elements.
