Golog (Golok[2] or Guoluo) Tibetan Autonomous Prefecture (Chinese: 果洛藏族自治州; pinyin: Guǒluò Zàngzú Zìzhìzhōu; Tibetan: མགོ་ལོག་བོད་རིགས་རང་སྐྱོང་ཁུལ་, Wylie: Mgo-log Bod-rigs rang-skyong-khul) is an autonomous prefecture occupying the southeastern corner of Qinghai province, China.

The prefecture has an area of 76,312 km2 (29,464 sq mi) and its seat is located in Maqên County.

[3] Golog Prefecture is located in the southeastern part of Qinghai, in the upper basin of the Yellow River.

However, these lakes do receive water from rivers that flow from locations even further west, in Qumarleb County of the Yushu Tibetan Autonomous Prefecture.

The existence of the ridge results in one of the great bends of the Yellow River, which first flows for several hundreds of kilometers toward the east and southeast along through the entire Golog Prefecture, along the southern side of the Amne Machin Range, until it reaches the borders of Gansu and Sichuan; it and then turns almost 180 degrees and flows toward the northwest for 200–300 km (120–190 mi) through several prefectures of the northeastern Qinghai, forming a section of the northeastern border of the Golog prefecture.
