Chan (; () of ), from Sanskrit dhyāna (meaning "meditation" or "meditative state"), is a Chinese school of Mahāyāna Buddhism. It developed in China from the 6th century CE onwards, becoming especially popular during the Tang and Song dynasties.
Chan is the originating tradition of Zen Buddhism (the Japanese pronunciation of the same character, which is the most commonly used English name for the school). Chan Buddhism spread from China south to Vietnam as Thiền and north to Korea as Seon, and, in the 13th century, east to Japan as Japanese Zen.

The historical records required for a complete, accurate account of early Chan history no longer exist.
The history of Chan in China can be divided into several periods. Zen, as we know it today, is the result of a long history, with many changes and contingent factors. Each period had different types of Zen, some of which remained influential while others vanished.
Ferguson distinguishes three periods from the 5th century into the 13th century:
The Legendary period, from Bodhidharma in the late 5th century to the An Lushan Rebellion around 765 CE, in the middle of the Tang dynasty. Little written information is left from this period. It is the time of the Six Patriarchs, including Bodhidharma and Huineng, and the legendary "split" between the Northern and the Southern School of Chan.
The Classical period, from the end of the An Lushan Rebellion around 765 CE to the beginning of the Song dynasty around 950 CE. This is the time of the great masters of Chan, such as Mazu Daoyi and Linji Yixuan, and the creation of the yü-lü genre, the recordings of the sayings and teachings of these great masters.
The Literary period, from around 950 to 1250, which spans the era of the Song dynasty (960–1279). In this time the gong'an-collections were compiled, collections of sayings and deeds by the famous masters, appended with poetry and commentary. This genre reflects the influence of literati on the development of Chan.
