The Sahrawi Republic, officially the Sahrawi Arab Democratic Republic (SADR; Spanish: República Árabe Saharaui Democrática; Arabic: الجمهورية العربية الصحراوية الديمقراطية‎‎ al-Jumhūrīyah al-‘Arabīyah aṣ-Ṣaḥrāwīyah ad-Dīmuqrāṭīyah) is a partially recognized state that controls a thin strip of area in the Western Sahara region and claims sovereignty over the entire territory of Western Sahara, a former Spanish colony. SADR was proclaimed by the Polisario Front on February 27, 1976, in Bir Lehlou, Western Sahara.

The SADR government controls about 20–25% of the territory it claims. It calls the territories under its control the Liberated Territories or the Free Zone. Morocco controls and administers the rest of the disputed territory and calls these lands its Southern Provinces. The SADR government considers the Moroccan-held territory to be occupied territory, while Morocco considers the much smaller SADR-held territory to be a buffer zone. The claimed capital of the SADR is El-Aaiún, while the temporary capital has been moved from Bir Lehlou to Tifariti.

The Sahrawi Republic maintains diplomatic relations with 40 UN states, and is a full member of the African Union.

Following the Spanish evacuation of Spanish Sahara, Spain, Morocco, and Mauritania signed the Madrid Accords on November 14, 1975, leading to both Morocco and Mauritania moving in to annex the territory of Western Sahara. On 26 February 1976, Spain informed the United Nations that as of that date it had terminated its presence in Western Sahara and relinquished its responsibilities, leaving no Administering Power. Neither Morocco nor Mauritania gained international recognition, and war ensued with the independence-seeking Polisario Front, claiming to represent the Sahrawi people.
