Curt Allen Byrum (born December 28, 1958) is an American professional golfer who has played on the PGA Tour and the Nationwide Tour. He is the older brother of PGA Tour golfer Tom Byrum.

Byrum was born and raised in Onida, South Dakota. He learned to play golf on a nine-hole course that he and brother Tom used to mow. He was an exceptionally talented athlete in high school in both football and basketball. Byrum attended the University of New Mexico and was a member of the golf team. He turned pro in 1982 and joined the PGA Tour in 1983.

Byrum has spent time playing on the PGA Tour and the Nationwide Tour. He has 19 top-10 finishes in PGA Tour events and 18 top-10 finishes in Nationwide Tour events. Like his brother, he won once on the PGA Tour; and also like his brother, that win came in 1989. He won twice on the Nationwide Tour. His best finish in a major is T-14 at the 1987 PGA Championship. Late in his career, Byrum began experiencing orthopedic ailments which limited his playing time; he had surgery on his right elbow in 1992 and 1996.

Since 2001, Byrum has worked with The Golf Channel as an analyst for the Nationwide Tour and the Canadian Tour. He lives in Scottsdale, Arizona.

Byrum made his Champions Tour debut in 2009 but has played only six events.
