The Dilmun Burial Mounds (Arabic: مدافن دلمون, romanized: Madāfin Dilmūn) are a UNESCO World Heritage Site comprising necropolis areas on the main island of Bahrain dating back to the Dilmun and the Umm al-Nar culture.

Bahrain has been known since ancient times as an island with a very large number of burials, the (originally) quite a number of square kilometres of mounds were said to be one of the largest cemeteries in the ancient world. The cemeteries are concentrated in the north of the island, on the hard stony areas slightly above the arable farming soils – the south of the island is mainly sandy and desert-like. Recent studies have shown that the estimated/approximately 350,000 ancient grave mounds could have been solely produced by the local population over a number of thousands of years. The graves are not all of the same era, or of exactly the same styles, and can vary considerably in size in different areas of the moundfield. Research, under the auspices of the Bahrain National Museum (with the Bahrain Historical and Archaeological Society taking a keen interest), is still continuing, to establish a firm timeline for all these variations and continuations, as well as considering the implications for the society or societies that produced them.
