Comprehensive Peace Agreement Day in South Sudan Date in the current year: January 9, 2025

Comprehensive Peace Agreement Day commemorates the signing of the Comprehensive Peace Agreement between the Government of Sudan and the rebel movement, the Sudan People's Liberation Army, in Naivasha, Kenya. The agreement ended the Second Sudanese Civil War, which began in June 1983.

The Second Sudanese Civil War was largely a continuation of the First Sudanese Civil War (1955–1972). After the first civil war ended, South Sudan gained more regional autonomy from the Anglo-Egyptian condominium. The Second Sudanese Civil War ended in 2005, resulting in South Sudan's independence from Sudan for six years as stated in the Comprehensive Peace Agreement.

A new referendum was held from January 9 to 15, 2011, to determine whether South Sudan would become an independent country separate from Sudan. Nearly the entire South Sudanese population voted for independence. July 9 is celebrated as the day South Sudan became an independent country.
