The prime minister of the Sahrawi Arab Democratic Republic is the head of government of the Sahrawi Arab Democratic Republic (SADR), a government in exile based in the Sahrawi refugee camps of Tindouf, Algeria. The post of the prime minister has been held by Bouchraya Hammoudi Bayoun since 13 January 2020.

The Sahrawi Arab Democratic Republic, also known as the Sahrawi Republic and Western Sahara, is a partially recognized state, recognized by 46 UN member states and South Ossetia, located in the western Maghreb, which claims the non-self-governing territory of Western Sahara, but controls only the easternmost one-fifth of that territory. Between 1884 and 1975, Western Sahara was known as Spanish Sahara, a Spanish colony. The SADR is one of the two African states in which Spanish is a significant language, the other being Equatorial Guinea.
