Ian Thomas Baldwin (born 1958) is an American ecologist.

Scientific career 
Baldwin studied biology and chemistry at Dartmouth College in Hanover, New Hampshire, and graduated 1981 with an AB. In 1989 he graduated with a PhD in chemical ecology from Cornell University, Ithaca, New York, Section of Neurobiology and Behavior. He was an Assistant (1989), Associate (1993) and Full Professor (1996) in the Department of Biology at SUNY Buffalo. In 1996 he became the Founding Director of the Max Planck Institute for Chemical Ecology where he heads the Department of Molecular Ecology. In 1999 he was appointed Honorary Professor at Friedrich Schiller University in Jena, Germany. In 2002 he founded the International Max Planck Research School at the Max Planck Institute in Jena.

Baldwin's scientific work is devoted to understanding the traits that allow plants to survive in the real world. To achieve this, he has developed a molecular toolbox for the native tobacco, Nicotiana attenuata (coyote tobacco), and a graduate program that trains "genome-enabled field biologists" to combine genomic and molecular genetic tools with field work to understand the genes that matter for plant-herbivore, -pollinator, -plant, -microbial interactions in nature. He has been a driver behind the Open Access publication efforts of the Max Planck Society and is one of the senior editors of the open access journal eLife. 
Since  November 2020, the Department of Molecular Ecology is led by Acting Director Sarah O’Connor.  The former Director Ian Baldwin now serves as Leader of the Research Group of a Scientific Member of the Max Planck Society (FG WiMi, Forschungsgruppe Wissenschaftliches Mitglied) and he continues his research at the Institute in this role.
