2010–11 NBA Development League season

The 2010–11 NBA Development League season is the tenth season of the NBA Development League (NBA D-League). The NBA D-League is the official minor league basketball organization owned and run by the National Basketball Association (NBA). The league was formed in 2001 as the National Basketball Development League (NBDL). The league adopted the "NBA D-League" name in 2005 to reflect its close affiliation with the NBA (a name it retained until 2017, when it was renamed the NBA G League). One expansion franchise, the Texas Legends, joined the 15 returning teams from the previous season.

The season started with the 2010 NBA Development League Draft, which was held on November 1, 2010. Former NBA second-round draft pick Nick Fazekas was selected first overall by the Reno Bighorns. The regular season began on November 18, 2010, and ended on April 4, 2011. The Iowa Energy had the best regular season record with 37 wins and 13 losses. They also won the Eastern Conference, while the Reno Bighorns won the Western Conference with the second-best regular season record with 34 wins and 16 losses. The regular season set a new record on total attendance of 1,125,583, a 7.9% increase from the previous season.

The playoffs started on April 6, 2011. The first seed, the Iowa Energy, defeated the Utah Flash and the Tulsa 66ers in the first and second round consecutively. The defending champion Rio Grande Valley Vipers, who was seeded third, defeated the Bakersfield Jam and the Reno Bighorns in the first and second round respectively. The Energy and the Vipers face each other in the 2011 NBA D-League Finals that was started on April 24, 2011. The Energy won the first game 123–106, while the Vipers won the second game 141–122 to even the series. On April 29, 2011, the Energy won the decisive Game Three to win their first ever championship.
