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. Vietnam accepted the convention on 19 October 1987, making its natural and cultural sites eligible for inclusion on the list. As of 2025, there are nine World Heritage Sites in Vietnam, including six cultural sites, two natural sites, and one mixed. Vietnam holds the second-highest number of World Heritage Sites in Southeast Asia, after Indonesia with ten sites.
