Shide was a Tang Dynasty Chinese Buddhist poet at the Guoqing Temple on Mount Tiantai on the East China Sea coast; roughly contemporary with Hanshan and Fenggan, but younger than both of them. As close friends the three of them formed the "Tiantai Trio". Shide lived as a lay monk, and worked most of his life in the kitchen of Guoqing Temple.
An apocryphal story relates how Shide received his name: Once, Fenggan was travelling between Guoqing Temple and the village of Tiantai, when at the redstone rock ridge called 'Red Wall' he heard some crying. He investigated, and found a ten-year-old boy who had been abandoned by his parents; and picked him up and took him back to the temple, where the monks subsequently raised him.
Shide is referred to as Jittoku in Japanese.
