2019–20 Oregon Ducks men's basketball team

The 2019–20 Oregon Ducks men's basketball team represented the University of Oregon during the 2019–20 NCAA Division I men's basketball season. The Ducks, led by 10th-year head coach Dana Altman, played their home games at Matthew Knight Arena as members of the Pac–12 Conference. They finished the season 24–7, 13–5 in Pac-12 play to win the regular season Pac-12 championship. They were set to take on rival Oregon State in the quarterfinals of the Pac-12 tournament. However, the Pac-12 Tournament, along with all postseason tournaments, was cancelled amid the COVID-19 pandemic.

Previous season
The Ducks finished the season with a 25–13 record, 10–8 in conference play, and finished tied for fourth in the Pac-12. As the 6 seed in the Pac-12 tournament, Oregon upset No. 3-seeded Utah, No. 2-seeded Arizona State, and No. 1-seeded Washington to win the tournament championship and receive the conference's automatic bid to the NCAA tournament. Oregon entered the NCAA Tournament as a No. 12 seed and upset the No. 5 seed Wisconsin in the first round. Oregon made it to the Sweet Sixteen where they lost to Virginia, who would eventually become National Champions.
