Brian Wansink is a former American professor and researcher who worked in consumer behavior and marketing research. He is the former executive director of the USDA's Center for Nutrition Policy and Promotion (CNPP) (2007–2009) and held the John S. Dyson Endowed Chair in the Applied Economics and Management Department at Cornell University, where he directed the Cornell Food and Brand Lab.

Wansink's lab researched people's food choices and ways to improve those choices. Starting in 2017, problems with Wansink's papers and presentations were brought to wider public scrutiny. These problems included conclusions not supported by the data presented, data and figures duplicated across papers, questionable data (including impossible values), incorrect and inappropriate statistical analyses, and "p-hacking". As of 2020 Wansink has had 18 of his research papers retracted (one twice), seven others have received an expression of concern, and 15 others have been corrected. On September 20, 2018, Cornell determined that Wansink had committed scientific misconduct and removed him from research and teaching activities; he resigned effective June 30, 2019.
