Madeleine McCann is a British child who disappeared at the age of three on May 3, 2007, from a holiday apartment in Praia da Luz, Portugal, where she was staying with her family. Her disappearance sparked one of the most heavily reported missing-person cases in modern history. Despite extensive investigations and search efforts by Portuguese, British, and German authorities, Madeleine's whereabouts remain unknown.

Her parents, Kate and Gerry McCann, left Madeleine and her twin siblings asleep in the apartment while dining nearby, but when they checked on the children, Madeleine was missing. Over the years, the case generated significant media attention worldwide, with fundraising efforts by the McCanns to aid the search and various appeals and campaigns to find her. The Portuguese police at one point suspected foul play, and the McCanns were briefly considered suspects, but these charges were dropped due to lack of evidence. Ongoing investigations continue, with occasional new leads or searches, including efforts by Operation Grange led by the Metropolitan Police. Recently, claims by a woman asserting to be Madeleine were investigated and ruled out by DNA tests.
