Savas Dimopoulos (Greek: Σάββας Δημόπουλος; born 1952) is a Greek particle physicist at Stanford University. He was born in Istanbul, Turkey and later moved to Athens due to ethnic tensions in Turkey during the 1950s and 1960s. Dimopoulos studied as an undergraduate at the University of Houston. He went to the University of Chicago and studied under Yoichiro Nambu for his doctoral studies. After completing his Ph.D. in 1979, he briefly went to Columbia University before taking a faculty position at Stanford University in 1980. During 1981 and 1982 he was also affiliated with the University of Michigan, Harvard University and the University of California, Santa Barbara. From 1994 to 1997 he was on leave from Stanford University and was employed by CERN.

Dimopoulos is well-known for his work on constructing theories beyond the Standard Model, which are currently being searched for and tested at particle colliders and in other experiments. For example in 1981 he proposed a softly broken SU(5) GUT model with Howard Georgi, which is one of the foundational papers of the Minimal Supersymmetric Standard Model (MSSM). He also proposed the "ADD" model of large extra dimensions with Nima Arkani-Hamed and Gia Dvali.

In 2006, the American Physical Society awarded Dimopoulos the Sakurai Prize, "For his creative ideas on dynamical symmetry breaking, supersymmetry, and extra spatial dimensions, which have shaped theoretical research on TeV-scale physics, thereby inspiring a wide range of experiments."[1]

Dimopoulos has one daughter, Christina.
