Al Da'asa (Arabic: دعسة‎) is an archaeological site located on the western coast of Qatar. It is the most extensive Ubaid site in the country. It was excavated by a Danish team in 1961. The site is theorized to have accommodated a small seasonal encampment, possibly a lodging for a hunting-fishing-gathering group who made recurrent visits. This is evidenced by the discovery of nearly sixty hearths at the site, which may have been utilized to cure fish, in addition to flint tools such as scrapers, cutters, blades and arrow heads. Furthermore, many painted Ubaid potsherds and a carnelian bead were found in the fire pits, suggesting overseas connections.
