Cambodian names (or Khmer names; ឈ្មោះខ្មែរ chhmŏăh khmêr) are names used or originating in Cambodia which usually consist of two elements including a patronymic, which serves as a common family name for siblings, followed by a given name (i.e. following the Eastern name order). An example is singer Sinn Sisamouth, his surname (last name) is Sinn and his given name (first name) is Sisamouth (in Western sources, the two are sometimes reversed).
The use of surnames in Cambodia is relatively recent and was not mandated by law until imposed by the French in 1910. Surnames are typically derived from the father's given name.
