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 in the book 1001 Movies You Must See Before You Die 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.
