The RAF Fauld explosion was a military accident which occurred at 11:11 am on Monday, 27 November 1944 at the RAF Fauld underground munitions storage depot. The RAF Fauld explosion was one of the largest non-nuclear explosions in history and the largest to occur on UK soil.

Between 3,500 and 4,000 tonnes of ordnance exploded—mostly comprising high explosive (HE)-filled bombs, but including a variety of other types of weapons and including 500 million rounds of rifle ammunition. The explosion crater with a depth of 300 feet (91 m) and 250 yards (230 m) across is still visible just south of Fauld, to the east of Hanbury in Staffordshire, England. It is now known as the Hanbury Crater  A nearby reservoir containing 450,000 cubic metres of water was obliterated in the incident, along with several buildings including a complete farm. Flooding caused by destruction of the reservoir added to the damage directly caused by the explosion.

The exact death toll is uncertain; it is believed that about 70 people died in the explosion.
