Dongguan Mosque, Islamic worship center in Chengdong District, China

Dongguan Mosque is a mosque on Dongguan Avenue in Chengdong District, Xining, covering 11,940 square metres, with a prayer hall of 1,102 square metres. Its cream lower facade has arched openings, a balustrade and rectangular panels bearing Arabic inscriptions; a large green-tiled central dome with a crescent finial stands beside a slender minaret banded in pale stone and green, and a light-green square pavilion with wooden windows under a dark curved tiled roof.

Built in 1380 under the Ming Hongwu emperor, the mosque was originally a single courtyard with a worship hall and two multi-storey minarets. Renovations were completed in the late 19th to early 20th century, followed by heavy damage from political conflict and restorations through the 20th century. Generals Ma Qi and Ma Bufang controlled it while governing Qinghai. In 2021 the green dome and minarets added in 2000 were removed in a remodel.

The mosque's name, Dongguan, comes from its site on Dongguan Avenue in Chengdong District. Generals Ma Qi and Ma Bufang controlled the mosque while they governed Qinghai. In 1989 and again in October 1993, worshippers gathered here to protest books they considered insulting to Islam; in 1993 troops entered and removed the protesters.

The site is accessible to visitors most days of the week, though opening hours may vary based on prayer times. It is best to check ahead for exact visiting times, as religious holidays and prayer schedules can affect access.

The green dome and the two minarets seen in older photographs were added in 2000 and removed in a 2021 remodel; the mosque committee stated the removed sections were not part of the protected relic. The complex was listed as a National Key Cultural Relic in 2013.
