The 2009 Air New Zealand Cup was the 33rd provincial rugby union competition, the fourth since the competition reconstruction in 2006, involving the top 14 provincial unions in New Zealand. It ran for 15 weeks from 30 July to 7 November. It was also the last edition of the provincial competition to use the Air New Zealand Cup name, as the competition's sponsorship contract with Air New Zealand ended after that season. The 2010 competition will be held under a new name, the ITM Cup.
