Blonde Cobra is a 1963 short film directed by experimental filmmaker Ken Jacobs. Footage for the unique and at the time controversial film was shot by Bob Flieshner. Marc Siegel states that the 33-minute film is "generally considered to be one of the masterpieces of the New York underground film scene", and that it is a "fascinating audio-visual testament to the tragicomic performance of the inimitable Jack Smith", who was a photographer and filmmaker and "queer muse" in New York avant-garde art in the 1960s and 1970s. The film is meant to be accompanied by the presence of a live radio during the screening.
