Irere (Spring/Summer 2003) was the twenty-first collection by British fashion designer Alexander McQueen for his eponymous fashion house. Irere was inspired by imagery from the Age of Discovery and from the people and animals of the Amazon rainforest. Its title is claimed to mean 'transformation' in an unspecified Indigenous Amazonian language. The collection comprised three distinct concepts presented as a narrative sequence: shipwrecked pirates, menacing conquistadors, and tropical birds. McQueen described the collection as an effort to present a more mature point of view and surprise viewers with bold colours.

The collection's runway show was staged on 5 October 2002 during Paris Fashion Week. The models walked around a bare white stage with a large screen for a backdrop. A film by John Maybury accompanied the show, depicting the phases of the collection's narrative. Fifty-six looks were presented. The most significant were the "shipwreck dress", worn by a model in the Maybury film, and the "oyster dress", a technically complex gown with a skirt made from hundreds of individual circles of organza, resembling an oyster shell. A skull-printed scarf presented in Irere became a trend and then a brand signature.

Response to the collection was positive, especially towards the oyster dress, which critics regarded as evidence of McQueen's evolving skills as a designer. Although some reviewers criticised the show's narrative, most felt that the colourful dresses of the third act were a strong finale. Many in the industry named Irere as one of their favourites for the season. Ensembles from Irere appeared in several magazine spreads following the show. Various museums hold items from the collection, some of which have appeared in exhibitions like the retrospective Alexander McQueen: Savage Beauty.
