Mark Lewis is an Australian documentary film and television producer, director and writer. He is famous for his film Cane Toads: An Unnatural History and for his body of work on animals. Unlike many other producers of nature films, his films do not attempt to document the animals in question or their behaviors but rather the complex relationships between people and society and the animals they interact with.

His films have earned him many awards, including a British Academy Award nomination, a nomination from the Directors Guild of America, two Emmy's for Outstanding Direction in documentary film, and an Emmy Award for Outstanding Science Program on American Television.
