Dao
Dao is a short surname found in several cultures, often as a transliterated East or Southeast Asian family name.
The #3,220 most common surname in the United States (2010 Census) — about 1 in every 27,540 Americans shares it.
Etymology
As a surname in modern use, Dao is usually not a single English-language family name with one fixed origin, but a romanized form of several different surnames from Asian languages. In Chinese contexts it may reflect different characters and meanings depending on the original spelling and dialect; in Vietnamese it can represent a separate native surname written Đào, often rendered without diacritics as Dao in English. Because the same spelling can cover different source names, the literal meaning is not uniform.
History
The surname appears in diaspora records in North America and elsewhere through immigration and later English-language standardization, where diacritics and tonal marks are often dropped. As a result, people recorded as Dao may come from more than one linguistic and family tradition. The surname is relatively uncommon in the United States, but it is recognizable in communities with Chinese, Vietnamese, and neighboring Southeast Asian heritage.

Fun fact
The same Latin-letter spelling can hide different original surnames, so two families named Dao may have unrelated histories.
