Guelmim (Arabic: كلميم, also spelt Glaimim, Goulimine or Guelmin), is a city in southern Morocco, often nicknamed Gateway to the Desert (la porte du désert). It is the capital of the Guelmim-Es Semara region which includes southern Morocco (south of the Souss-Massa-Drâa region) and northern Western Sahara. The population of the city is 117 000 (2006 census), 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-Drâa.
Guelmim is located just north of Asrir, which was the site of an important trade-route city and the capital of the Saharan tribes. It was known in Arabic sources as Noul Lamta.
It is home to a camel market. When hippies "discovered" certain types of colorful African trade beads there in the 1960s, these became known as "Goulamine beads" though they were actually manufactured in Europe, primarily in Venice, Italy.
Many of the inhabitants speak the Hassaniya dialect, as it is part of the Sahrawi-inhabited southern region of Morocco.
