Duckett spent the last six years on the staff at South Carolina. He built a 150-75 record over eight years as the head coach at NCAA Division II Fayetteville State and Winston-Salem State.
"Coach Duckett is a proven tactician who has worked with some of the best coaches in the business," said Grambling Athletic Director Troy Mathieu. "He has a unique ability to motivate and connect with student-athletes and will bring tremendous enthusiasm to our men's basketball program."
Duckett replaces Larry Wright, who had an 88-160 record over nine seasons at Grambling. The Tigers were 7-19 last season.
