Ha
A short surname found especially in East and Southeast Asia, often reflecting a Chinese, Korean, or Vietnamese family name or romanization.
The #1,987 most common surname in the United States (2010 Census) — about 1 in every 17,005 Americans shares it.
Etymology
Ha is a very short surname that can arise from several different East Asian naming traditions, so it does not have one single universal origin. In Chinese contexts it may reflect a surname written with a character pronounced approximately "He" or "Xia" in modern Mandarin under some romanization systems or dialect spellings; in Korean it can represent the family name 하, usually romanized Ha; and in Vietnamese it may correspond to surnames written with similar sounds in local transcription. Because the spelling is shared by multiple languages, the literal meaning depends on the specific family and original script.
History
As a romanized surname, Ha became more visible in English-language records through immigration from East Asia in the 19th and 20th centuries. In the United States it is especially associated with families of Korean, Vietnamese, and Chinese background, though the same spelling can mask different original surnames. The short form can also result from simplified or inconsistent transliteration in older documents.

Fun fact
Because the spelling is so brief, Ha is one of those surnames where the same English form can hide completely different family histories and original characters.
