2009–10 Atlantic 10 Conference men's basketball season

The 2009–10 Atlantic 10 Conference men's basketball season marks the 34th season of Atlantic 10 Conference basketball.

Preseason
In the preseason, talk centered around the University of Dayton, who returned four starters from a 27–8 team that advanced to the second round of the 2009 NCAA tournament. Dayton forward Chris Wright was named to the John R. Wooden Award preseason top 50 candidate list on August 19, the only Atlantic 10 player so honored. Wright also was named to the Naismith Award watch list on October 29. In other preseason recognition, Jason Duty of Duquesne and Yves Mekongo of La Salle were named to the 30-man preseason candidate list for the Lowe's Senior CLASS Award.

In a vote of league coaches and media, Dayton was named the preseason favorite to win the league. Dayton also received national recognition as the Flyers were ranked in both preseason polls – #21 in the AP Poll and #22 in the ESPN/USA Today Coaches' poll.
