A queen dowager or dowager queen (compare: princess dowager or dowager princess) is a title or status generally held by the widow of a king. In the case of the widow of an emperor, the title of empress dowager is used. Its full meaning is clear from the two words from which it is composed: queen indicates someone who served as queen consort (i.e. wife of a king), while dowager indicates a woman who continues to hold the title from her deceased husband (a queen who reigns in her own right is a queen regnant). A queen mother is a former queen consort, often a dowager queen, who is the mother of the reigning monarch.
As of 2025, there are three queens dowager: Kesang Choden of Bhutan (who is the only living queen grandmother worldwide), Norodom Monineath of Cambodia (who is also queen mother), and Lisa Najeeb Halaby (Noor Al'Hussein) of Jordan.
