Christopher Ian Byrnes (June 28, 1949 – February 7, 2010) was an American mathematician and control theorist. He was the Edward H. and Florence G. Skinner Professor Emeritus of Systems Science and Mathematics at Washington University in St. Louis and served as dean of the School of Engineering & Applied Science from 1991 to 2006.

Byrnes made foundational contributions to nonlinear control, output regulation, distributed parameter systems, and geometric methods in control theory. Together with Tryphon T. Georgiou and Anders Lindquist, Byrnes was a founder of the so-called Byrnes–Georgiou–Lindquist school, which developed a new moment-based approach for the solution of control and estimation problems with complexity constraints.
