Social ownership is a type of property where an asset is recognized to be in the possession of society as a whole rather than individual members or groups within it. Social ownership of the means of production is the defining characteristic of a socialist economy, and can take the form of community ownership, state ownership, common ownership, employee ownership, cooperative ownership, and citizen ownership of equity. Within the context of socialist economics it refers particularly to the appropriation of the surplus product, produced by the means of production, or the wealth that comes from it, to society at large or the workers themselves. Traditionally, social ownership implied that capital and factor markets would cease to exist under the assumption that market exchanges within the production process would be made redundant if capital goods were owned and integrated by a single entity or network of entities representing society. However, the articulation of models of market socialism where factor markets are utilized for allocating capital goods between socially owned enterprises broadened the definition to include autonomous entities within a market economy.

Socialism is an economic and political philosophy encompassing diverse economic and social systems characterised by social ownership of the means of production, as opposed to private ownership. It describes the economic, political, and social theories and movements associated with the implementation of such systems. Social ownership can take various forms, including public, community, collective, cooperative, or employee. Traditionally, socialism is on the left wing of the political spectrum. Types of socialism vary based on the role of markets and planning in resource allocation, and the structure of management in organizations.
