Cultural heritage is the tangible and intangible legacy of a group or society that is inherited from past generations. Not all legacies of past generations are "heritage"; rather, heritage is a product of selection by society.

Cultural heritage includes tangible culture (such as buildings, monuments, landscapes, archive materials, books, works of art, and artifacts), intangible culture (such as folklore, traditions, language, and knowledge), and natural heritage (including culturally significant landscapes, and biodiversity). The term is often used in connection with issues relating to the protection of Indigenous intellectual property.

The deliberate action of keeping cultural heritage from the present for the future is known as preservation (American English) or conservation (British English), which cultural and historical ethnic museums and cultural centers promote, though these terms may have more specific or technical meanings in the same contexts in the other dialect. Preserved heritage has become an anchor of the global tourism industry, a major contributor of economic value to local communities.

Legal protection of cultural property comprises a number of international agreements and national laws. United Nations, UNESCO and Blue Shield International deal with the protection of cultural heritage. This also applies to the integration of United Nations peacekeeping.

Cultural property includes the physical, or "tangible" cultural heritage, such as artworks. These are generally split into two groups of movable and immovable heritage. Immovable heritage includes buildings (which themselves may include installed art such as organs, stained glass windows, and frescos), large industrial installations, residential projects, or other historic places and monuments. Moveable heritage includes books, documents, moveable artworks, machines, clothing, and other artifacts, that are considered worthy of preservation for the future. These include objects significant to the archaeology, architecture, science, or technology of a specified culture.

Aspects and disciplines of the preservation and conservation of tangible culture include:

"Intangible cultural heritage" consists of non-physical aspects of a particular culture, more often maintained by social customs during a specific period in history. The concept includes the ways and means of behavior in a society and the often formal rules for operating in a particular cultural climate. These include social values and traditions, customs and practices, aesthetic and spiritual beliefs, artistic expression, language and other aspects of human activity. The significance of physical artifacts can be interpreted as an act against the backdrop of socioeconomic, political, ethnic, religious, and philosophical values of a particular group of people. Naturally, intangible cultural heritage is more difficult to preserve than physical objects.^{[citation needed]}
