Ximen (Chinese: t=西門|s=西门|p=Xīmén) is a Chinese compound surname. Ximen literally means "west gate", the origination story says that there was a noble family in Zheng or Qi state live near the west gate, so the descendants took Ximen (west gate) as their family name. As compound surnames are rare in China, some Ximen families have changed their name to the single surname Xi(西).
