Alan Wilson Watts (6 January 1915 – 16 November 1973) was an English writer, speaker, and self-styled "philosophical entertainer", known for interpreting and popularising Buddhist, Taoist, and Hindu philosophy for a Western audience.

Watts gained a following while working as a volunteer programmer at the KPFA radio station in Berkeley. He wrote more than 25 books and articles on religion and philosophy, introducing the Beat Generation and the emerging hippie counterculture to The Way of Zen (1957), one of the first best selling books on Buddhism. In Psychotherapy East and West (1961), he argued that psychotherapy could become the West's way of liberation if it discarded dualism, as the Eastern ways do. He considered Nature, Man and Woman (1958) to be, "from a literary point of view—the best book I have ever written". He also explored human consciousness and psychedelics in works such as "The New Alchemy" (1958) and The Joyous Cosmology (1962).

His lectures found posthumous popularity through regular broadcasts on public radio, especially in California and New York, and more recently on the internet, on sites and apps such as YouTube and Spotify. The bulk of his recorded audio talks were recorded during the 1960s and early 1970s.
