Ian Hinchliffe (born 1952) is a British physicist at Lawrence Berkeley National Laboratory.
In 1983 he became a Staff Senior Scientist at Lawrence Berkeley National Laboratory, where he served as head of the theoretical physics group from 1992 to 1999.
His research emphasizes the importance of experiment in testing theoretical ideas, and in driving theoretical developments aimed at understanding interactions among fundamental particles.
Much of his research looks to show how the Standard Model can be tested at hadron colliders.
In 2011, Ian Hinchliffe, Chris Quigg, Estia Eichten, and Kenneth Lane won the J. J. Sakurai Prize for Theoretical Particle Physics "for their work, separately and collectively, to chart a course of the exploration of TeV scale physics using multi-TeV hadron colliders".
