Mexico has the highest number of UNESCO World Heritage Sites among North American countries.
Mexico’s total reached 36 World Heritage properties in 2025, keeping it ahead of Canada and the United States. The count includes cultural, natural and mixed sites, ranging from historic city centers and archaeological zones to protected landscapes and biosphere reserves. The Wixárika Route through Sacred Sites to Wirikuta became Mexico’s newest World Heritage inscription in 2025.
Mexico’s large total reflects its exceptional cultural and geographic diversity. Ancient civilizations left major sites such as Teotihuacan, Chichén Itzá and Palenque, while colonial history produced protected centers including Mexico City and Oaxaca. Natural properties include the Monarch Butterfly Biosphere Reserve and the Islands and Protected Areas of the Gulf of California.
Counts can change when UNESCO adds new properties, so this question is time-sensitive. “North America” can also be defined differently in school geography, but under the standard continental grouping—including Mexico, Canada and the United States—Mexico is the clear answer.
