Henry Valentine Miller was an American novelist and painter. He was renowned for breaking with existing literary forms and developing a new sort of 'novel' that is a mixture of novel, autobiography, social criticism, philosophical reflection, surrealist free association, and mysticism. These works are distinctly always about and expressive of the real-life Henry Miller and yet are also fictional.

His most characteristic works include Tropic of Cancer, Tropic of Capricorn, and Black Spring. He also wrote travel memoirs and essays on literary criticism and analysis.

Miller's novels often featured explicit language and content, leading to controversies and bans in the United States until 1961. His work had a significant influence on the Beat Generation.
