Robert W. Duden (September 5, 1920 – March 22, 1995) was an American professional golfer who played on the PGA Tour in the 1950s and 1960s.

A lifelong resident of Portland, Oregon, Duden compiled a remarkable record in sectional golf competition.

He won over 50 tournaments in a 40-year career that included 23 major Pacific Northwest Section events including a record 7 wins of the Pacific Northwest Senior PGA Championship;[1] he won the Oregon Open a record eight times.

[1][5] When other well-known professionals like Sam Snead adopted this revolutionary putting technique, its popularity began to surge; however, the USGA banned it when traditionalists like Bobby Jones objected.

In his later years, he worked as a teaching pro at Glendoveer Golf Course, where an annual tournament bears his name.
