Guelmim (Arabic: كلميم|kulmīm, ڭلميم|gulmīm, گليميم|gleymīm, ⴳⵯⴻⵍⵎⵉⵎ|gʷelmim; also spelled in European sources: Glaimim, Goulimine or Guelmin) is a city in southern Morocco, often called Gateway to the Desert. It is the capital of the Guelmim-Assif Noun region which includes southern Morocco (south of the Souss-Massa region) and the northeastern corner of Western Sahara. The population of the city was 187,808 as of the 2014 Moroccan census,[1] making it the largest city in the region. The N1 and N12 highways cross at Guelmim and link it to the nearby region of Souss-Massa.
Guelmim is located just north of Asrir, which was the site of an important trade-route city and the capital of the Saharan Berber tribes. It is home to a camel market. Most of the inhabitants speak either the Tachelhit language or the Hassaniya dialect of Sahrawi Arabs, as it is part of the Sahrawi-inhabited southern region of Morocco.
Guelmim has a hot desert climate (Köppen climate classification BWh).
