Victor Hamazaspovich Hambardzumyan was a Soviet Armenian scientist, and one of the founders of theoretical astrophysics. He worked in the field of physics of stars and nebulae, stellar astronomy, dynamics of stellar systems and cosmogony of stars and galaxies, and contributed to mathematical physics.

Hambardzumyan founded the Byurakan Observatory in 1946. He was the second and longest-serving president of the Armenian Academy of Sciences (1947–93) and also served as the president of the International Astronomical Union from 1961 to 1964 and was twice elected the President of the International Council of Scientific Unions (1966–72)
