The Idaho Stampede is an American basketball team that plays in the NBA Development League. The team is based in the Boise, Idaho, area. Since 2005 they have played at the CenturyLink Arena in Boise. The team was founded as a member of the Continental Basketball Association in 1997 and was league runner-up in the 2003–04 season, losing to the Dakota Wizards. After the 2005–06 season, the Stampede announced that the team would be joining the NBA Development League. The Stampede's sole NBA affiliate is the Portland Trail Blazers, with whom they have a hybrid partnership. In the Stampede's first D-League season, the team won the Western Division title, tying for the best record in the league.
On April 25, 2008, the Stampede defeated the Austin Toros, 108–101, in Game 3 of the D-League finals. It was the first title in team history in either the CBA or the D-League. Ever since they lost to the Austin Toros in the 2009 NBA Development League Playoffs, they've never returned to the playoffs, with a 70-80 record for the past three seasons. Earlier in the season, in January 2008, the team had hosted the annual D-League Showcase, in which all the league's teams played two games each in a five-day period.
