Private property is a legal designation for the ownership of property by non-governmental legal entities. Private property is distinguishable from public property, which is owned by a state entity, and from collective or cooperative property, which is owned by a group of non-governmental entities.

Private property is foundational to capitalism, an economic system based on the private ownership of the means of production and their operation for profit. The distinction between private and personal property varies depending on political philosophy, with socialist perspectives making a hard distinction between the two. As a legal concept, private property is defined and enforced by a country's political system.
