The current flag of Sudan (Arabic: علم السودان, romanized: ʿalam as-Sūdān) was adopted on 20 May 1970 and consists of a horizontal red-white-black tricolour with a green triangle at the hoist. The flag is based on the Arab Liberation Flag of the Egyptian Revolution of 1952, as are the flags of Egypt, Iraq, Syria, Yemen, and Palestine and formerly of the United Arab Republic, North Yemen, South Yemen, and the Libyan Arab Republic.

Whereas there is no fixed order for the Pan-Arab Colours of black, white, red, and green, flags using the Arab Liberation Colours (a subset of the Pan-Arab Colours) maintain a horizontal triband of equal stripes of red, white, and black, with green being used to distinguish the different flags from each other by way of green stars, Arabic script, or, in the case of Sudan, the green triangle along the hoist. In the original Arab Liberation Flag, green was used in the form of the flag of the Kingdom of Egypt and Sudan emblazoned on the breast of the Eagle of Saladin in the middle stripe. For 13 years from Sudan's independence in 1956 to the 1969 military coup of Gaafar Nimeiry, Sudan used a tricolour flag of blue-yellow-green.
