Count: 0 — No sovereign Asian countries start with the letter D. This count follows standard English short names for UN-member states and widely recognized transcontinental countries with territory in Asia. Note that several well-known Asian places begin with D (for example, Dubai, Delhi and Damascus), but these are cities or regions rather than independent countries.

Understand why the list is empty. Country names in English reflect local languages, historical borders and colonial-era naming, and the letter D is simply uncommon as an initial in those official short names. Long formal titles can begin with D — for example, the Democratic People’s Republic of Korea uses a D in its full name — but conventions alphabetize and cite the commonly used short name (North Korea), so it does not count as a country starting with D. Also exclude dependent territories and unrecognized micro-claims (for example, Diego Garcia is a territory), which would otherwise confuse a clear, sovereign-country list.

Consult authoritative sources for verification. Check the UN member list, the CIA World Factbook or World Bank country lists for official English short names and recognition status. If you seek D‑names in the region, search instead for Asian cities that start with D, countries that contain the letter D (India, Thailand), or look through the A–Z country lists for adjacent letters.
