Guantánamo is a municipality and city in southeast Cuba and capital of Guantánamo Province.

Guantánamo is served by the Caimanera port and is the site of a U.S. Naval base. The area produces sugarcane and cotton wool. These are traditional parts of the economy.

The municipality is mountainous in the north, where it overlays the Sierra Maestra (mountains), and borders the Windward Passage of the Caribbean Sea in the south. It is crossed by the Guantánamo, Yateras, Guaso, San Andrés and Sabanalamar rivers. The Guantánamo Bay is a natural harbour south of the city.

The municipality is divided into the barrios of Arroyo Hondo, Baitiquirí, Bano, Bayate, Caimanera, Camarones, Caridad, Corralillo, Cuatro Caminos, Filipinas, Glorieta, Gobierno, Guaso, Hospital, Indios, Isleta, Jaibo Abajo, Las Lajas, Macurijes, Mercado, Ocujal, Parroquia, Palma de San Juan, Rastro, Tiguabos and Vínculo.

About 15 km away from the city lies the Guantánamo Bay, a superior natural harbor which has been controlled by the United States as the Guantánamo Bay Naval Base since 1902, following the Platt Amendment decree. It is the site of the Guantanamo Bay detention camp.
