Joanna Karine Hoffman is an American marketing executive. She was one of the original members of both the Apple Computer Macintosh team and the NeXT team. At the time she began at Apple Computer, the Mac was "still a research project". Her position "constituted the entire Macintosh marketing team for the first year and a half of the project," which included Product Marketing collaboration on the Mac product design itself. She also wrote the "first draft of the Macintosh User Interface Guidelines." Hoffman would eventually run the International Marketing Team which brought the Mac to Europe and Asia.
