Jiaoshi Yilin (Chinese: 焦氏易林; pinyin: Jiāoshì Yìlín; literally: "Forest of Changes by Jiao") is a Chinese book of divination composed during the Western Han Dynasty. Modeled on the I Ching, the work was attributed to Jiao Yanshou (焦延壽, see zh:焦贛), though not much is known about the author. He is said to have been the teacher of Jing Fang.
The work was one of the few surviving books of divination produced in that period of Chinese history. It contains 64 x 64 = 4096 hexagrams (I Ching contains 64); each of the hexagram is commented by a short poem (3-8 lines; each line comprises, in most cases, 4 characters). Besides its historical value, the work has also been treasured for its literary merit.
