The 2009–10 Oregon Ducks men's basketball team represented the University of Oregon in the 2009–10 college basketball season. This was head coach Ernie Kent's 13th and final season at Oregon. The Ducks played their home games at McArthur Court and were members of the Pacific-10 Conference. They finished the season 16–16, 7–11 in Pac-10 play and lost in the quarterfinals of the 2010 Pacific-10 Conference men's basketball tournament. They were not invited to a post season tournament and Ernie Kent was fired at the end of the season, leading to an extensive coaching search in the subsequent offseason.
