The Black Book: Imbalance of Power and Wealth in the Sudan, known commonly as the Black Book (Arabic: الكتاب الأسود al-kitab al-aswad), is a manuscript detailing a pattern of disproportionate political control by the people of northern Sudan and marginalization of the rest of the country. It was published in two parts, the first in May 2000 and the second on August 2002. While published anonymously, it was later revealed that the writers had strong ties to the Justice and Equality Movement, a rebel group active in the conflict that later erupted in Darfur to the west.
