Fernanda Bertini Viégas (born 1971) is a Brazilian computer scientist and graphical designer, whose work focuses on the social, collaborative and artistic aspects of information visualization.

The same year she began work at IBM's Thomas J. Watson Research Center in Cambridge, Massachusetts, as part of the Visual Communication Lab.

In April 2010, she and Martin M. Wattenberg started a new venture called Flowing Media, Inc., to focus on visualization aimed at consumers and mass audiences.

Her work with visualizations such as History Flow and Chromogram led to some of the earliest publications on the dynamics of Wikipedia, including the first scientific study of the repair of vandalism.
