The United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage Sites are places of importance to cultural or natural heritage as described in the UNESCO World Heritage Convention, established in 1972. Cultural heritage consists of monuments (such as architectural works, monumental sculptures, or inscriptions), groups of buildings, and sites (including archaeological sites). Natural heritage consists of natural features (physical and biological formations), geological and physiographical formations (including habitats of threatened species of animals and plants), and natural sites which are important from the point of view of science, conservation, or natural beauty. Romania accepted the convention on 16 May 1990, making its historical sites eligible for inclusion on the list.

, there are 11 World Heritage Sites in Romania, nine of which are cultural sites and two of which are natural. The first site in Romania, the Danube Delta, was added to the list at the 15th Session of the World Heritage Committee, held in Carthage in 1990. Further sites were added in 1993 and 1999 and some of the sites were subsequently expanded. Roșia Montană Mining Cultural Landscape was listed in 2021 and was immediately placed in the list of World Heritage in Danger due to plans to resume mining. The site Ancient and Primeval Beech Forests of the Carpathians and Other Regions of Europe is shared among 18 European countries. In addition, there are 19 sites on Romania's tentative list. __TOC__
