48, by the same rule as every continent on this site
The 48 figure follows the UN's M49 geographic classification, the same source behind this site's world total of 195 and its European count of 44. Under that scheme, Türkiye, Cyprus, Armenia, Georgia, and Azerbaijan are all classified as Asian, even though each sits at the edge of Europe geographically, culturally, or institutionally. Egypt, despite the Sinai Peninsula's location east of the Suez Canal, is classified as African in full, since the vast majority of its land and population sit on the African side. Neither placement is a factual error; both are the UN's own dividing lines for a landmass that has never had a single, universally agreed border with its neighboring continents.
Why published answers range from 46 to 51
Lower counts, closer to 46, usually treat Türkiye, Cyprus, and the Caucasus states as European instead, subtracting them from Asia's total. Higher counts, closer to 51, add Taiwan as an independent country. Taiwan governs itself, has its own military, currency, and elections, and meets most working definitions of statehood, but it is not a member of the United Nations: the UN transferred China's seat from the Republic of China, based in Taipei, to the People's Republic of China in 1971, and while eleven UN member states still maintain formal diplomatic relations with the Republic of China, no state maintains official relations with both Taipei and Beijing at once. This site follows the UN member and observer state list everywhere, which is why Taiwan is not one of the 195 countries in the Geography app or in this count of 48, a decision explained in full on the Taiwan sovereignty explainer. A reader who wants Taiwan included is not wrong to count it; they are using a different, defensible standard for what counts as a country.
All 48, by subregion
The UN groups Asia into five subregions: Central, Eastern, South-eastern, Southern, and Western Asia. Western Asia is the largest with 18 countries, most of them in the Middle East and the Gulf; Central and Eastern Asia are the smallest, with 5 each. Here is every country this site counts, with its capital and subregion.

Largest, smallest, and most populous
By land area, China is Asia's largest country, at roughly 9.56 million square kilometers, well ahead of India at about 3.29 million and Kazakhstan at about 2.72 million. Russia would be larger still if it were counted here rather than in Europe. By population, India has overtaken China as the continent's and the world's most populous country, with a UN estimate of about 1.46 billion people in 2025 against China's roughly 1.41 billion, a crossover the UN population division dated to April 2023, after decades of China holding the top spot. At the small end, the Maldives is Asia's smallest country by land area, a scatter of islands totaling around 300 square kilometers, while Brunei, on the island of Borneo, has the smallest population of any Asian country, at about 466,000 people.
