Anthony James Leggett (born March 26, 1938), is Professor of Physics at the University of Illinois in Urbana-Champaign . He is widely recognized as a world leader in the theory of low-temperature physics , and his pioneering work on superfluidity was recognized by the 2003 Nobel Prize in Physics. He has shaped the theoretical understanding of normal and superfluid helium liquids and other strongly coupled superfluids. He set directions for research in the quantum physics of macroscopic dissipative systems and use of condensed systems to test the foundations of quantum mechanics.

He is a member of the National Academy of Sciences, the American Philosophical Society, the American Academy of Arts and Sciences, the Russian Academy of Sciences (foreign member), and is a Fellow of the Royal Society (U.K.), the American Physical Society, and the American Institute of Physics . He is an Honorary Fellow of the Institute of Physics (U.K.).

His current research focuses on cuprate superconductivity, conceptual issues in the foundations of quantum mechanics, and superfluidity in highly degenerate atomic gases.
