The 2019–20 Duquesne Dukes men's basketball team represented Duquesne University during the 2019–20 NCAA Division I men's basketball season.

The Dukes, led by third-year head coach Keith Dambrot, were members of the Atlantic 10 Conference (A-10).

Their season ended when the A-10 tournament and all other postseason tournament were canceled due to the ongoing coronavirus pandemic.

Due to the closure of the Dukes' normal home of UPMC Cooper Fieldhouse (formerly Palumbo Center) for major renovations, the team used three venues for its home games: Kerr Fitness Center at La Roche University in the northern suburb of McCandless, UPMC Events Center at Robert Morris University in the northwest suburb of Moon Township, and PPG Paints Arena in downtown Pittsburgh.

7 seed in the A-10 tournament, they lost to Saint Joseph's in the second round.
