Corse-du-Sud (French pronunciation: [kɔʁs dy syd] ; Corsican: Corsica suttana [ˈkorsiga zutˈtana], Pumonte [puˈmɔntɛ] or Pumonti [puˈmɔnti]; English: Southern Corsica) is (as of 2019) an administrative department of France, consisting of the southern part of the island of Corsica. The corresponding departmental territorial collectivity merged with that of Haute-Corse on 1 January 2018, forming the single territorial collectivity of Corsica, with territorial elections coinciding with the dissolution of the separate council. Although its administrative powers were ceded to the new territorial collectivity, it continues to remain an administrative department in its own right. In 2019, it had a population of 158,507.

The department was formed on 1 January 1976, when the single department of Corsica was divided into Haute-Corse and Corse-du-Sud. Its boundaries corresponded to the former department of Liamone, which existed from 1793 to 1811.

On 6 February 1998, Corse-du-Sud's prefect Claude Érignac was assassinated in Ajaccio. The Corsican nationalist Yvan Colonna was eventually convicted of the crime.

On 6 July 2003 a referendum rejected increased autonomy by a small majority, with 50.98 percent voting against and 49.02 percent for. This was a major setback for the French Minister of the Interior, Nicolas Sarkozy, who had hoped to use Corsica as the first step in his decentralization programme.

On 1 January 2018, Corse-du-Sud's administrative powers were partly ceded to the new territorial collectivity of Corsica.

The department is surrounded on three sides by the Mediterranean Sea and on the north by the department of Haute-Corse. The entire island of Corsica is mountainous with many beautiful beaches.

The most populous commune is Ajaccio, the prefecture. As of 2019, there are 3 communes with more than 4,000 inhabitants:

Commune	Population (2019)
Ajaccio	71,361
Porto-Vecchio	11,132
Bastelicaccia	4,124

The people living in Corse-du-Sud are called Suttanacci.

The former department enjoys the mild and hot climate of Mediterranean Islands, and therefore attracts a lot of tourists. Its perhaps largest tourist attraction is the city of Bonifacio, part of which is built upon a huge cliff. But inside mountains are beautiful as well, especially the Aiguilles de Bavella, some naked, needle-like rocks.
