Tamtam tracks 320 companies headquartered in Algeria. This list ranks the 100 largest by number of employees on LinkedIn, led by Sonatrach, Lidl Italia and sonelgaz. Their median headcount is 1,002. Half of them were founded in 1991 or later.

🇩🇿 Algeria100 companiesUpdated Nov 12, 2026

The largest companies in Algeria are primarily state-owned enterprises in the oil and gas, telecommunications, and utilities sectors, alongside some significant private groups. Sonatrach, a government-owned company, exploits hydrocarbon resources, while Sonelgaz provides electricity and gas. Algérie Telecom and Naftal Spa are also prominent, with the former in telecommunications and the latter distributing petroleum products.

Most of these companies are well-established, with many founded in the mid to late 20th century. A notable pattern is the strong presence of state-owned entities, reflecting significant government involvement in key industries such as energy and communication. Several major players like Sonatrach, Sonelgaz, and Algérie Telecom have their headquarters in or around Alger, highlighting the capital region's importance as a business hub.

How this list is built

Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 12, 2026.
