Edward Rolf Tufte (IPA /ˈtʌf.ti/) (born 1940) is a professor emeritus of statistics, graphic design, and political economy at Yale University and an expert in the presentation of informational graphics, such as infographics, charts and graphs. He is a fellow of the American Statistical Association and has held fellowships from the Guggenheim Foundation and the Center for Advanced Studies in Behavioral Sciences .

Tufte's work is important in such fields as information design and visual literacy, which deal with the visual communication of information. He coined the term "chartjunk" to refer to useless, non-informative, or information-obscuring elements of information displays; Tufte's work argues strongly against the inclusion of any decoration in visual presentations of information, and claims that ink should only be used to convey significant data and aid its interpretation.

Tufte also developed Sparklines, "data-intense, design-simple, word-sized graphics".
