Guanyin Bridge, Stone arch bridge in Mount Lu, Jiangxi, China.

Guanyin Bridge is a single-arch granite bridge over Sanxia Stream, 24.45 m long, 4.94 m wide and 10.7 m high, with a clear span of 10.33 m. Its 107 granite blocks are fitted together with mortise-and-tenon joints and no mortar. The arch centre bears an inscription dated to the seventh year of Dazhong Xiangfu (1014).

Built in 1014 under Emperor Zhenzong of the Song dynasty, the bridge was first called Qixian Bridge after the nearby Qixian Temple, and also Sanxia Bridge for the Sanxia Stream it crosses. In the Qing dynasty a Cihang Temple was built before it, and the bridge took the name Guanyin from the temple's deity. It was listed as a provincial cultural relic in 1959 and a national one in 1988.

Following the establishment of Cihang Temple during the Qing dynasty, the structure received its present name from Guanyin, the Buddhist goddess of compassion worshipped at the nearby temple, reflecting how the crossing became associated with spiritual pilgrimage and religious devotion in the mountain landscape.

Access is available through hiking trails in the Mount Lu area of Jiangxi, with the crossing itself forming part of the historical route to Cihang Temple and best viewed during dry weather when the stream below runs low and the stone structure remains clearly visible.

The arch's central keystone bears a carved inscription dated to the seventh year of the Dazhong Xiangfu era (1014), naming the reigning emperor and praying for good harvests and peace. Other stones record the monks Wenxiu of Jianzhou and Zhilang of Fuzhou who organised the work, and the Jiangzhou masons Chen Zhifu, Chen Zhiwang and Chen Zhihong.
