Yanshi District[2] (simplified Chinese: 偃师区; traditional Chinese: 偃師區; pinyin: Yǎnshī Qū) is a district in the prefecture-level city of Luoyang in western Henan province, China.

Yanshi lies on the Luo River and is the easternmost county-level division of Luoyang.

When Qin annexed Zhou in 256 BC, Yanshi County was established.

[7] Erlitou is the name of the modern village nearby; the traditional name of the settlement was Zhenxun (斟鄩, Zhēnxún).

In 1983, a walled city dating from 1600 BC was found 6 km (3.7 mi) north-east of the Erlitou site in Yanshi's Shixianggou Township.
