Bruce Carl Berndt (born March 13, 1939, in St. Joseph, Michigan) 
is an American mathematician. Berndt attended college at Albion College, graduating in 1961, where he also ran track. He received his master's and doctoral degrees from the University of Wisconsin–Madison. He lectured for a year at the University of Glasgow and then, in 1967, was appointed an assistant professor at the University of Illinois at Urbana-Champaign, where he has remained since. In 1973–74 he was a visiting scholar at the Institute for Advanced Study in Princeton. He is currently () Michio Suzuki Distinguished Research Professor of Mathematics at the University of Illinois.

Berndt is an analytic number theorist who is probably best known for his work explicating the discoveries of Srinivasa Ramanujan. He is a coordinating editor of The Ramanujan Journal and, in 1996, received an expository Steele Prize from the American Mathematical Society for his work editing Ramanujan's Notebooks. A Lester R. Ford Award was given to Berndt, with Gerd Almkvist, in 1989 and to Berndt, with S. Bhargava, in 1994.

In 2012 he became a fellow of the American Mathematical Society.
In December 2012 he received an honorary doctorate from SASTRA University in Kumbakonam, India.
