This article is about the Ming Dynasty Chinese eunuch. For other historical figures with this name, see Wang Zhen (disambiguation).
Wáng Zhèn (王振) was the first Ming Dynasty eunuch with power in the court. The Zhihua Si Temple in Beijing was built in 1443 at his order.
He was killed (possibly by Ming officers) during the Tumu Crisis (also known as the Battle of Tumu Fortress), a disastrous campaign against the Oirat Mongols for which he was responsible.
