Don Bies (born December 10, 1937) is an American professional golfer who has won tournaments on the PGA Tour, the Senior PGA Tour (now known as the Champions Tour), and in the Pacific Northwest Section of the PGA of America.

Born in Cottonwood, Idaho, Bies attended Ballard High School in Seattle, Washington and turned pro in 1957. His only PGA Tour win came at the 1975 Sammy Davis Jr.-Greater Hartford Open. His best finish in a major was a T-5 at the 1968 U.S. Open which was played at Oak Hill Country Club in Rochester, New York. Bies is a three-time winner of the Washington Open (stroke play) and a six-time winner of the Washington State Match Play Championship and has won a host of other events in the Pacific Northwest. He left the PGA Tour in 1980 in order to devote full-time to his restaurant he had opened just outside Seattle.

After turning 50 at the end of 1987, Bies joined the Senior PGA Tour, where his fortunes improved dramatically with respect to winning tournaments. He has won numerous events both on the regular Senior PGA Tour and in non-Tour senior events. These wins include a senior major championship - The Tradition at Desert Mountain in 1989.

Bies was elected a member of the Pacific Northwest PGA Hall of Fame in 1994. He lives in Seattle with his wife of more than 50 years, Marylin. They have three grown children: Karen, Marcy and David; and eight grandchildren.
