The Chastity Arch for Qiu Liang-gong's Mother () is a paifang in Jincheng, Kinmen, Taiwan.
Qiu Liang-gong was born in Kinmen. His father died 35 days after his birth, leaving his mother alone to raise him. Her mother never remarried. Qiu grew up later to become a military officer in the navy. His mother was then honored and the arch was constructed for her in 1812.
The arch is a four-pillar, three-section stone structure made of granite and limestone. There are four pairs of stone lions located at the front and back sides of the pillar.
