The extension was approved by the board of trustees on Friday. The extension puts Keatts under contract for seven seasons, through 2025-2026.
"NC State has become home for my family and I, we're grateful to Chancellor Woodson and Director of Athletics Boo Corrigan for their commitment and the opportunity to continue to lead the Wolfpack," said Keatts. "I look forward to building on the foundation we've created, and to leading NC State for many years to come."
Keatts, who came to State after a tenure at UNC Wilmington, has led the Wolfpack to a 45-24 record in his first two seasons in Raleigh.
