Shaab Abu Nuhas, or Shab Abu Nuħas (Arabic: شعب أبو النحاس |translit=Shaʿb Abū an-Nuḥās), is a triangular-shaped coral reef northwest of Shadwan Island in the northern Red Sea off Hurghada.
The reef is a navigation hazard because it projects into the shipping channel, as evidenced by (at least) seven shipwrecks. This includes the SS Carnatic (1896),[1] Kimon M (1978), Olden (1987), Chrisoula K (1981)[2] and Giannis D (1983).[3] The reef and the wrecks are popular for scuba diving; four of the wrecks are at a depth of more than 30m (100feet).[4] The name of the reef is Arabic for "reef of father of copper", after the cargo of one of the wrecks.
