Hassi

Hassi is a North African toponym commonly found in Algeria and neighboring countries. The term derives from Arabic and is used in many desert settlements to indicate a well or water source. As a result, it appears as a prefix or element in numerous place names.

Notable places include Hassi Messaoud, a town in Ouargla Province, Algeria, which grew around one of the country’s largest oil fields discovered in the 1950s and became a central driver of Algeria’s oil industry. Hassi R'Mel is a major natural gas field in central Algeria, one of the largest globally, and a cornerstone of the national gas sector since its development in the latter half of the 20th century.

In addition to these sites, the toponym Hassi appears in many other Algerian and Maghrebi localities, and in some cases as a surname in North Africa and the diaspora.

The usage of Hassi illustrates how water availability shaped settlement patterns in arid regions and how toponymy preserves historical and economic associations with natural resources.
