Joaquin (Quin) Mazdak Luttinger (December 2, 1923 – April 6, 1997) was an American physicist well known for his contributions to the theory of interacting electrons in one-dimensional metals[1] (the electrons in these metals are said to be in a Luttinger-liquid state) and the Fermi-liquid theory.

He received his BS and PhD in physics from MIT in 1947.

[2] His brother was the physical chemist Lionel Luttinger (1920–2009) and his nephew is the mathematician Karl Murad Luttinger (born 1961).
