Chén (Simplified Chinese: 陈, Traditional Chinese: 陳) is one of the four most common Chinese family names (its exact position varies depending on the set of statistics used). It is occasionally romanized Chern in Mandarin Chinese (where "r" indicates the second tone in the Gwoyeu Romatzyhromanization system). It is usually romanized as Chan in Cantonese, sometimes as Chun, Chin or Zen. Some other Romanizations (from other Chinese languages) include Tan and Ding.
Chen is also a Hebrew family name used by Israelis. It is pronounced khen, and meaning grace or favor.
