Lucy Yi Zhenmei[a] (December 9, 1815 – February 19, 1862) was a Sichuanese Catholic saint from Mianyang, Sichuan Province, China.

[6] After her father died, she lived with her brother and mother, using part of her leisure time to catechise children nearby.

The parish priest, who asked her to teach at the school in Mianyang, noticed her devotion and reliable knowledge of her faith.

[6] In 1862, she went with Jean-Pierre Néel [fr], a missionary priest of Paris Foreign Missions Society, to start a mission in Jiashanlong, but just then the administrator of Guizhou Province, Tian Xingshu, began to stir up hatred against Christians, with the support of the local magistrate.

Pope John Paul II canonized Lucy Yi Zhenmei and her companions, the Martyr Saints of China, on October 1, 2000.

[7] Lucy Yi Zhenmei is honored (with Agatha Lin Zhao and Agnes Tsao Kou Ying) with a Lesser Feast on the liturgical calendar of the Episcopal Church in the United States of America[8] on February 19.
