هيو دايفيد بولتيزر hugh david Politzer (مواليد 31 أغسطس1949) عالم فيزياء نظريةأمريكي.

حصل على جائزة نوبل للفيزياء بالاشتراك مع فرانك ويلكزكودايفيد غروس عام 2004 عن اكتشافاتهما في الحرية المتقاربة في مجال كروموديناميكا كوانتية.

Politzer was born in New York City to a Jewish family. He graduated from the Bronx High School of Science in 1966, received his bachelor's degree from the University of Michigan in 1969, and his PhD in 1974 from Harvard University, where his graduate advisor was Sidney Coleman.
In his first published article, which appeared in 1973, politzer described the phenomenon of asymptotic freedom: the closer quarks are to each other, the weaker thestrong interaction will be between them. When quarks are in extreme proximity, the nuclear force between them is so weak that they behave almost like free particles. This result—independently discovered at around the same time by Gross and Wilczek at Princeton University—was extremely important in the development of quantum chromodynamics. With Thomas Appelquist, Politzer also played a central role in predicting the existence of "charmonium", an subatomic particle formed of a charm quark and a charm antiquark.
Politzer was a junior fellow at the Harvard Society of Fellows from 1974 to 1977 before moving to the California Institute of Technology (Caltech), where he is currently professor of theoretical physics. In 1989 he appeared in a minor role as Manhattan Project physicist Robert Serber in the movie Fat Man and Little Boy.
