Václav Edvard "Vic" Beneš (born 1931) is a Czech-American mathematician, known for his contributions to the theory of , queueing theory and control theory, as well as the design of telecommunications switches.

He studied under John Kemeny and gained a doctorate in mathematics at Princeton University (1953) on a treatise on Mathematical logic.

He then worked for Bell Labs until 1986, contributing to Kalman filter theory as well as the Beneš network, a permutation network of the Clos network type. In the 1980s he held a position at Columbia University as well. He has continued to publish independently since 1989.

He was elected IEEE Fellow (1991) for "contributions to the structure of telephone connecting networks, , and nonlinear filtering". The Benesfest was celebrated at Columbia University (2001) to honor his 70th birthday. He resides in Millburn, New Jersey (since 1985) where he has been a long-time mountain climber member of the American Alpine Club, and currently heads the local historical society.

He is a relative of the former President of Czechoslovakia Edvard Beneš and politician Vojta Beneš. Emilie Benes Brzezinski, a sculptor, is his sister.
