This selection of large public sector organizations in Saudi Arabia includes entities primarily focused on energy, education, and national development. Noteworthy companies include aramco, a global energy and chemicals producer; SABIC, a leader in chemical manufacturing; and SAUDI AIRLINES, the national carrier. The list also features major educational institutions like King AbdulAziz University and King Saud University, alongside significant healthcare providers such as the Ministry of National Guard Health Affairs.

A prominent trend among these organizations is their substantial role in national infrastructure and economic diversification. Many are headquartered in Riyadh, the capital, reflecting a centralization of major public entities. Examples include Qiddiya, developing a large-scale entertainment city, and Red Sea Global, a luxury tourism developer, both contributing to the country's vision for new industries and job creation.

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.
