Asia is the largest and most populated continent in the world. The population of Asia makes up about 60% of the world population. It shares the continental landmass of Eurasia with the continent of Europe, and the continental landmass of Afro-Eurasia with Africa and Europe. In general terms, Asia is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a historical and cultural construct, as there is no clear physical and geographical separation between them.

The PRC, DPRK, Vietnam, and Laos are all located in Asia. Russia is commonly considered to span both Europe and Asia, with most of Russia's territory being located in the Asian continent, while most of the country’s population resides in the European side. Kazakhstan also has contiguous territory in both Europe and Asia. The Ural River, which flows into northwestern Kazakhstan, is considered to be part of the border between Europe and Asia. Turkey is also commonly considered to be located in both Europe and Asia. Egypt is a country whose territory is located mostly in North Africa. A part of Egyptian territory, known as the Sinai Peninsula, is considered to be part of Asia and serves as a land bridge between Africa and Asia.

Asia varies greatly across and within its regions with regard to ethnic groups, cultures, environments, economics, historical ties and government systems. It also has a mix of many different climates including desert, subtropical, temperate, subarctic, and polar areas.

Regions

Asia is often conceptually divided into several subregions, although there is no universal consensus on these divisions, and many have overlapping or flexible demarcations.

Some commonly described regions of Asia include Central Asia, East Asia, South Asia, Southeast Asia, West Asia (also commonly called the Middle East), and North Asia (also commonly called Siberia).
