In Algerian law, institutions are generally divided into two main categories:
* Public Institutions:
* These are entities belonging to the state or established to serve the public interest.
* They include the State (with all its branches: the Presidency, the Government, Parliament, the Judiciary), Territorial Collectivities (Wilayas and Communes), and Public Establishments (such as universities and hospitals, or public industrial and commercial enterprises).
* Private Institutions:
* These are entities established by individuals or private entities for profit or non-profit objectives.
* They include Companies (commercial and civil), Associations (non-profit), Foundations, Trade Unions, and Cooperatives.
In brief, Algerian law encompasses both governmental and administrative institutions serving the public good, and private institutions meeting diverse economic and social needs.
