Charles Joseph Colbourn (born October 24, 1953) is a Canadian computer scientist and mathematician, whose research concerns graph algorithms, combinatorial designs, and their applications.

From 1996 to 2001 he was the Dorothean Professor of Computer Science at the University of Vermont; since then he has been a professor of Computer Science and Engineering at Arizona State University.

[1][2][3] Colbourn was born on October 24, 1953, in Toronto, Ontario; despite working in the United States since 1996 he retains his Canadian citizenship.

[1] He did his undergraduate studies at the University of Toronto, graduating in 1976; after a master's degree at the University of Waterloo, he returned to Toronto for a Ph.D., which he received in 1980 under the supervision of Derek Corneil.

[1][5] In 2004, the Institute of Combinatorics and its Applications named Colbourn as that year's winner of their Euler Medal for lifetime achievements in combinatorics.
