Lei (雷) Surname Meaning & Origin

Lei (雷) is a common Chinese surname. While 雷 has a literal meaning as a character, surnames don’t always reflect personal traits-the character is best read as a family label.

A Chinese surname is both a practical identifier and a cultural marker that connects a person to family history. For the surname Lei (雷), it’s helpful to understand how Chinese surnames generally formed and why the same surname can show up with different spellings.

Many surnames began as the names of ancient states, fiefs, places of origin, or titles held by ancestors. Others developed from clan names, occupations, or honorifics. Over time, migration, administrative records, and local dialects shaped how a surname was written and pronounced.

Across different periods, families moved for work, study, military service, and trade. These migrations spread surnames widely and also created regional pronunciation differences. Because romanization converts sound into Latin letters, the same surname can appear with multiple spellings in English.

When in doubt, keep the Chinese character as the source of truth and treat different spellings as pronunciation-based variants.
