Name
The Chinese name "Tianzhu" was named by a Tibetan lama Luo Haoxue (罗好学) in 1936, deriving from the combination of "Tiantang" (天堂寺, aka Chortentang Monastery) and "Zhugong" (祝贡寺, aka Drigung Monastery), the Chinese translation of the two largest lamaseries in the county.

The Tibetan name Bairi is pronounced Bairi in Standard Tibetan, and pronounced Hwari in the local Amdo Tibetan and Huarui (华锐) in Chinese.

An alternative Tibetan name is Tenzhu, which is a transcription of the Chinese name Tianzhu.

History
The county was established as the Tianzhu District of Yongdeng County in 1949, but became an autonomous county of Wuwei in the next year. In 1955, Tianzhu was moved under the administration of Zhangye as the first autonomous county in China. Between 1958 and 1961, Gulang County was part of Tianzhu. In 1961 the county was placed under Wuwei again.
