# 50 leading public sector organisations in Algeria

Tamtam tracks 84 public sector organisations headquartered in Algeria. This list ranks the 50 largest by number of employees on LinkedIn, led by Sonatrach, sonelgaz and Algérie Telecom. Their median headcount is 1,125. Half of them were founded in 1981 or later.

These are large public sector organizations in Algeria, primarily focusing on essential services and natural resources. Notable examples include Sonatrach, a major player in oil and gas, and Sonelgaz, which handles electricity and gas supply. Algérie Telecom provides telecommunications services, while Naftal spa distributes petroleum products across the country.

The majority of these entities are state-owned and have a significant number of employees. A common pattern is the strong presence of companies in the oil and gas sector, along with key infrastructure and public service providers. Several companies were founded in the 1960s and 1980s, indicating periods of significant state-led development.

## 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.
