Sudanese Arabic is the variety of Arabic spoken throughout Sudan. It has much borrowed vocabulary from the local languages (El Rotana). This has resulted in a variety of Arabic that is unique to Sudan, reflecting the way in which the country has been influenced by both African and Arab cultures. Some of the tribes in Sudan still have similar accents to the ones in Saudi Arabia.

In 1888 the Journal of the Royal Anthropological Institute of Great Britain claimed that the Arabic spoken in Sudan was "a pure but archaic Arabic". The pronunciation of certain letters was like Syrian, and not Egyptian, such as g being the pronunciation for Qaf and J being the pronunciation for Jim.

Sudanese Arabic is distinct from Egyptian Arabic and does not share some of the characteristic properties of that dialect despite the overall similarity of the two dialects.

The Arabic letter ج maintains an archaic pronunciation [ɡʲ] in Sudanese (other dialects typically have [dʒ], [ʒ] or [j], while Egyptian Arabic has [ɡ]).
