Jingwan (Chinese: 靜琬; pinyin: Jìngwǎn) (died 639) was a Buddhist monk who flourished in the 7th Century, based at Yunju Temple, Fangshan, China. Inspired by apocalyptic stories of the decline of Buddhism, in about 609 CE he conceived a project to carve Buddhist sutras onto stone tablets or steles to preserve them. The project began ca. 611 with major donations from the Empress and her brother Xiao Yu in 611 CE. Other donations soon followed and Leiyin Cave was completed ca 616 CE. Once begun, the project was to continue, off and on, for 1000 years and produced the most extensive collection of sutra engravings in China.
