Savas Dimopoulos (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 proposing many of the leading theories beyond the Standard Model, which are currently being searched for and tested at particle colliders and in other experiments. His best known work was development of the Minimal Supersymmetric Standard Model (MSSM) which he proposed in 1981 with Howard Georgi. He also proposed the theory of large extra dimensions with Nima Arkani-Hamed and Gia Dvali. For proposing these theories and influencing the field of theoretical particle physics he won the Sakurai Prize in 2006.
