Zheng He (1371–1433), formerly romanized as Cheng Ho, is a Hui-Chinese court eunuch, mariner, explorer, diplomat and fleet admiral, who commands voyages to Southeast Asia, South Asia, the Middle East, Somalia and the Swahili coast, collectively referred to as the "Voyages of Zheng He" from 1405 to 1433.

As a favorite of the Yongle Emperor, whose usurpation he assists, he rises to the top of the imperial hierarchy and serves as commander of the southern capital Nanjing.

These voyages were long neglected in official Chinese histories but have become well known in China and abroad since the publication of Liang Qihao's "Biography of Our Homeland's Great Navigator, Zheng He" in 1904.

A trilingual stele left by the navigator was discovered on Sri Lanka shortly thereafter.
