Zhang (surname 章)
Zhāng is a Chinese surname. According to a 2013 study it was the 122-most common surname, shared by 1,570,000 people or 0.120% of the population, with the province with the most people being Zhejiang. It is the 40th name on the Hundred Family Surnames poem.

The surname written  in Chữ Nôm is clearly distinguished and written as Trang or Chương. 章 was unlisted among the top 100 in either location. In 2015 it was reported 88th.

 combines the characters  (yin, "sound", "(musical) note") and  (shi, "ten"). It originally meant "brilliant", "to display", "a distinctive mark" and was used as the name of a fief, but as a common noun in modern use it means an "article" in a newspaper or magazine or a "chapter" in a book or law.

The surname  (Old Chinese: *taŋ) originated from the legendary Yan Emperor, whose personal surname was Jiang (). On the establishment of the state of Qi, Jiang Ziya apportioned the land among his many descendants, including a one known as Zhang (). Some of the people of this state simplified the character and took  as their surname, particularly after it was annexed by Qi. The Middle Chinese pronunciation of the name was Tsyang, the beginnings of what we now know to be the "Zhang" surname.

It means "stamp, seal" in Chinese.
