The 2011–12 NBA Development League season was the 11th 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 its current name in 2005 to reflect its close affiliation with the NBA. The 2011–12 season will be competed by 16 teams. The Los Angeles D-Fenders, after spending one season inactive, joined the 15 returning teams from the previous season. The Utah Flash ceased operation at the end of the previous season and would not be playing in the 2011–12 season. The New Mexico Thunderbirds relocated to Canton, Ohio and were renamed as the Canton Charge.

Five of them, the Austin Toros, the Canton Charge, the Dakota Wizards, the Los Angeles D-Fenders and the Tulsa 66ers, are owned by their NBA affiliates. Four teams, the Erie BayHawks, the Rio Grande Valley Vipers, the Springfield Armor and the Texas Legends, have a hybrid single-affiliation partnership with NBA teams, where their basketball operations are controlled by their NBA affiliates. The other seven teams are affiliated with three NBA teams each.

Players An NBA D-League team roster consists of draftees, returning, allocation and tryout players. In addition, NBA teams can assign players who are on their first or second NBA season to their D-League affiliates. The roster must consist of 10 D-League players, but the maximum roster size is 12 players, including NBA assignees. If a team had more than two NBA assignees, the team must reduce its roster to avoid having more than 12 players. In the D-League, all players sign a one-year NBA D-League Standard Player Contract with the league, not with the specific D-League teams.

Returning players are players who played in the league during the previous season and are retained by their respective teams. The D-League teams are allowed to invite a limited number of returning players. Players who signed a D-League contract but are not retained by their previous teams are placed on the draft pool, along with new players who also sign with the league. Tryout players are the players who are invited to join the D-League team from the open tryouts which are held by each teams in October, before the season began.
