Bonnie Lynn Bassler (born 1962) is an American molecular biologist; the Squibb Professor in Molecular Biology and chair of the Department of Molecular Biology at Princeton University; and a Howard Hughes Medical Institute Investigator. She has researched cell-to-cell chemical communication in bacteria and discovered key insights into the mechanism by which bacteria communicate, known as quorum sensing. She has contributed to the idea that disruption of chemical signaling can be used as an antimicrobial therapy.

She is an elected member of the National Academy of Sciences (as of 2006), a Foreign Member of the Royal Society (as of 2012), a former president of the American Society for Microbiology (2011) and served on the National Science Board with a term expiring May 10, 2016. She was an editor of the Annual Review of Genetics from 2012 to 2017.
