Bir Tiguisit, Buir Tiguisit or Bir Tighissit (Arabic: بير تيغیسیت|links=no) is a locality located in the southern part of Saguia el-Hamra, in Western Sahara. It is located south of Tifariti, near the border with Mauritania. It is currently controlled by the Polisario Front, in the so-called Liberated Territories or Free Zone. The Moroccan authorities have integrated it into the Es-Semara Province in the region of Laâyoune-Sakia El Hamra.
The demining carried out by MINURSO has made this population revitalized.[1] It consists of a small hospital,[2] a school[1] and some small shops.
Bir Tiguisit is located near the remains of the old Spanish colonial town of Colomina and one of the bases of MINURSO.[3]
