Rā's Būjādūr; Berber languages: ⴱⵓⵊⴷⵓⵔ, Bujdur; Spanish and Portuguese: Cabo Bojador; French: Cap Boujdour) is a headland on the west coast of Western Sahara, at 26° 07' 37"N, 14° 29' 57"W (various sources give various locations: this is from the Sailing Directions for the region), as well as the name of the large nearby town with a population of 42,651.

It is shown on nautical charts, media and academic research with the original Portuguese name "Cabo Bojador", sometimes spelled "Cape Boujdour".

The cape is not prominent on maps but may be located by looking 220 km (120 nautical miles) due south of the south-western point of the hook of Fuerteventura, Canary Islands.

The reason for the fearsome reputation of the cape is not immediately obvious from maps, where it appears as the south-western point of a slight hump in the coastline, bounded at its other end by Cabo Falso Bojador, ten nautical miles to the northeast.

Nor does what is said in the Sailing Directions sound terribly formidable: Cabo Falso Bojador is formed by several tall sand dunes ... A rocky shoal, with a least depth of 4.8m, extends up to 3 miles N of the cape.

Together with the half-knot set of current down the coast, these conditions would naturally alarm a medieval mariner used to sailing close to the land and having no knowledge of what lay ahead.

In addition, this is also believed to be the site where Captain James Riley and the crew of the U.S. brig Commerce, sailing at the time from Gibraltar towards the Cape Verde Islands, shipwrecked in August 1815.

The reason for all this display is because Cape Bojador and its surrounding coast extends into the sea in the form of an underwater reef, and, when the waves break after crashing into unseen gullies, the water spouts furiously into high foamy clouds that look like steam, even on calm days.

[8] As recently as 2004, the British Royal Navy's publication Africa Pilot warns that nautical charts of the coastline in the area of Cape Bojador are "reported to be inaccurate".

Spanish fishers were seal fur traders and hunters, fishers and whalers off the Sahara coast with several enclaves in Cabo Bojador, Dakhla and Ras Nouadhibou from 1500 to present, extending from the west coast of Africa to hunting humpback whales and whale calves, mostly in Cape Verde, and the Gulf of Guinea in Annobón, São Tomé and Príncipe islands just to 1940.

In January 2016 it was announced that the Canary Association of Victims of Terrorism (ACAVITE) intended to sue the Polisario Front for committing "crimes against humanity".
