The Flower Sermon is a story of the origin of Chan and Zen Buddhism in which Gautama Buddha transmits direct prajñā (wisdom) to the disciple Mahākāśyapa. In the original Chinese, the story is Niān huā wéi xiào (拈花微笑, meaning "Picking up a flower and smiling"). It appears as Case 6 in the Zen koan collection, The Gateless Barrier (Wúménguān; Jap. Mumonkan).

The Buddha affirmed this by saying:
History The story of the Flower Sermon appears to have been recorded by Chinese Chan Buddhists. The earliest known version of the tale appeared in 1036.
