The Sahrawi National Union Party (Arabic: حزب الاتحاد الوطني الصحراوي, romanized: Hizb Al-Ittihad Al-Qawmi Aṣ-Ṣaḥrāwīyyah; Spanish: Partido de Unión Nacional Saharaui, PUNS) was a short-lived political party set up by Francoist Spain to rally indigenous support in its rebellious Spanish Sahara colony (presently Western Sahara).

Its leaders and creators, Khellihenna Ould Errachid and Dueh Sidna Naucha, worked in close collaboration with Spanish authorities.

In addition to this, Polisario remained distrustful, and did not accept the demand of PUNS leaders to form a common political front while preserving the party's internal structure.

[4] In the night of November 14, 1975, the remaining members of the party, headed by last Secretary General Dueh Sidina Naucha, dissolved the PUNS, giving the affiliates the chance to join the Polisario Front.

A small number, including some prominent leaders, instead went to Morocco, where they denounced their own earlier nationalist campaign and lent their support to the claims of King Hassan II to Western Sahara — notably, PUNS leader Khellihenna Ould Errachid, who still today (2012) acts as the Moroccan monarchy's main Sahrawi face to its claims to Western Sahara.

[citation needed] A very small number of activists went to Mauritania, supporting the Ould Daddah government's claims on the territory until its collapse in 1978.
