An Nafud or Al-Nefud or The Nefud (Arabic,صحراء النفود, ṣahrā' al-nefud) is a desert in the northern part of the Arabian Peninsula at 28°18′N 41°00′E / 28.30°N 41.00°E, occupying a great oval depression. It is 290 kilometres (180 mi) long and 225 kilometres (140 mi) wide, with an area of 103,600 square kilometres (40,000 sq mi).
The Nafud is an erg, noted for its sudden violent winds, which account for the large crescent-shaped dunes. The sand in the Nafud is a brick reddish color. Rain comes once or twice a year. In some lowland areas, namely those near the Hejaz Mountains, there are oases where dates, vegetables, barley, and fruits are raised. The Nefud is connected to the Rub' al Khali by the Dahna, a corridor of gravel plains and sand dunes, 800 mi (1,287 km) long and 15 to 50 miles (24.1 to 80.5 km) wide.
Before the Battle of Aqaba (during the Arab Revolt) forces led by Auda ibu Tayi attacked the Turkish-held coastal town of Aqaba on its poorly defended eastern flank, achieved by taking a long and wide desert route, passing close to the edge of the Nafud. Col. T. E. Lawrence asked Auda ibu Tayi to allow their group to stray from their course into the Nafud. Auda refused, because it was unnecessary. Their harsh transit did not include entering the Nafud, as is depicted in the film Lawrence of Arabia.
