Linxia County (simplified Chinese: 临夏县; traditional Chinese: 臨夏縣; pinyin: Línxià Xiàn; Wade–Giles: Lin-hsia Hsien, Xiao'erjing: ‌لٍ‌ثِيَا ثِيًا) is a county in the Linxia Hui Autonomous Prefecture, province of Gansu, China.

Linxia County is located in central and south-western parts of the Linxia Hui Autonomous Prefecture, extending from the shores of Liujiaxia Reservoir in the north (at 1735 m elevation above the sea level, the lowest part of the county), to Taizu Mountains in the south and Dalijia Mountain (达里加山, دَالِ‌ڭِيَا شًا) (at 4613 m elevation above the sea level, the highest point in the county) in the west.

The county seat is located at Hanji Town (韩集镇, خًاڭِ جٍ), 24 km (15 mi) southwest of Linxia City.

[3] While most detailed (prefecture-level) maps label that location accordingly, less detailed (provincial) maps simply mark it as "Linxia County" (临夏县), which still makes it distinct from the county seat (labeled "Linxia City" (临夏市)).

The main ethnic groups represented were Han Chinese (221,419 or 59.2% of the total), Hui (121,680 or 32.4%) and Dongxiang (29,782 or 8%).

[7] Lanzhou Prefecture was abolished in 1913, and the Linxia area was included into Daohe County (导河县) with the capital in Jiachengguan Town (郊城关镇) (part of today's Linxia City), which in its turn was part of Lanshan Circuit (Dao).
