Ad-Dahna Desert is the central division of the Arabian Desert.^[1] It is a corridor of sandy terrain forming a bow-like shape that connects an-Nafud desert in the north to Rub' al-Khali desert in the south. Its length is more than 1,000 km (620 mi) siding Twaik Mountains from the east and does not exceed 80 km (50 mi) in width. It is also considered the geographical margin separating Al-Ahsa Province from Najd. Al-Dahna Desert is therefore the string that connects the great deserts of Saudi Arabia.

The desert is a series of seven successive deserts, separated from one another by plains.^[2] Roads pass through Al-Dahnā, linking Kuwait with Al-Zilfī and Riyadh and connecting Riyadh with Hasa.^[2]

Al-Dahna desert is formed of high sand dunes spreading horizontally which are called veins (Arabic: عُرُوْق, romanized: ʿUrūq), mostly red in color since it contains Iron Oxides.
