Hadijat Gatayeva (also transliterated Hadizhat Gataeva or Khadijad Gataeva) is a Chechen Muslim humanitarian activist who, together with her husband Malik, took care of some of the Grozny's war orphans. She is usually referred to just as Hadijat. Gatayeva and her children were one of the subject of the 2005 documentary film The 3 Rooms of Melancholia (Melancholian 3 huonetta) by Pirjo Honkasalo, who kept in contact with her ever since. Hadijat is also the titular "angel" in the 2008 book Angel of Grozny: Orphans of a Forgotten War by Åsne Seierstad.
