Ivan Goff (17 April 1910 – 23 September 1999) was an Australian screenwriter, best known for his collaborations with Ben Roberts including White Heat (1949), Man of a Thousand Faces (1957), Legend of the Lone Ranger (1981), and the pilot for Charlie's Angels (1976).

Goff was born in Perth, the son of two concert musicians. He attended Perth Boys High School (1922) and Perth Modern School (1923-26), and grew up in Claremont.

At 15, he began writing for a local newspaper, but soon became dissatisfied with the isolation he felt. "Living in Australia made me crazy", he later said in an interview. "It took a month for a book to get to Australia, a year for a play and forever for an idea."
