Kenneth Anger (born February 3, 1927) is an American underground avant-garde film-maker and author.

Kenneth Anger grew up in Hollywood and started out as a child actor, but his interest in filmmaking was evident at an early age: he made his first film, "Who's Been Rocking My Dreamboat?", at age 9. Anger developed into one of the pioneers of the American underground film movement. His gritty, violent, often homosexual-themed films were too strong for American audiences of the time, and many of his productions were filmed in Europe, mainly France. However, Anger is best known for authoring the landmark "Hollywood Babylon" books, which detailed a far more seamier side of the Hollywood film industry than most people were aware of.

Kenneth Anger is an independent filmmaker and author. He claims to have appeared as the child prince in A Midsummer Night's Dream (1935), but Warner Brothers production reports and casting sheets conclusively document that a little girl, child actress Sheila Brown, actually played the role. Anger did, however, begin making films at an early age. Most of his films are short experimental works, ranging from 3.5-30 minutes. His career has been recognized with life achievement awards from the Los Angeles Film Critics, the San Francisco International Film Festival, the Silverlake Film Festival, the Mar del Plata Film Festival, and the Maya Deren Award for Experimental Film/Life Achievement Award from the American Film Institute. Among other notable honors, he received the Poetic Film Prize at Festival du Film Maudit in Biarritz, France in 1949, which was presented by Jean Cocteau. Anger's work has screened around the world, including at the Institut Francais de Vienne in Austria, the Galerie Agnes B. in Paris, the National Film Theatre in London and Anthology Film Archive in New York. He is the author of Hollywood Babylon I & II. Education.
