The Ping River (Thai: แม่น้ำปิง, rtgs: Maenam Ping, IPA: [mɛ̂ːnáːm piŋ]), along with the Nan River, is one of the two main contributaries of Chao Phraya River. It originates at Doi Thuai, Daen Lao Range, in Chiang Dao district, Chiang Mai Province. After passing Chiang Mai town, it flows though the provinces Lamphun, Tak, and Kamphaeng Phet. At the confluence with the Nan River at Nakhon Sawan (also named Paknam Pho in Thai) it forms the Chao Phraya River.
The Ping Basin is one of the largest drainage basins of the Chao Phraya Watershed, draining 33,896 square kilometres (13,087 sq mi) of land.
The greater Ping Basin, i.e. the basin of the entire Ping river system including its tributary the Wang River, drains a total of 44,688 square kilometres (17,254 sq mi).
The main dams in the basin are the Bhumibol Dam and the Doi Tao Dam.
The Ping itself originates in Huai Nam Dang National Park and flows through Mae Ping National Park.
