驾崩，也做崩、山陵崩，宾天，是在汉文化圈中表示天子死亡的委婉说法。

驾崩源自《礼记·曲礼下》：“天子死曰崩”。“驾”则出自《后汉书·舆服志》“天子出，有大驾，有法驾，有小驾”。亦称“宫车晏驾”（语出《史记·范睢蔡泽列传》）、“龙驭上宾”（语出《史记·封禅书》）等。天子崩殂后，七日而殡，七月而葬。崩驾则指皇后﹑太后等逝世。

宾天典故出于黄帝，相传黄帝最后乘龙返回天界离开人间，称「龙驭宾天」，故宾天也成了天子死亡的委婉说法。元周密《齐东野语·卷十七·龚孟戣策问》：「明年秋，度宗宾天。」宾天有时也可指达官贵人之死，而非仅针对天子。

The demise of the Crown is the legal term for the end of a reign by a king, queen, or emperor, whether by death or abdication.

The term was coined in English law to signify the immediate transfer (Law French demise, "sending down [the line of succession]," from Latin demiss-[gender ending], the perfect participle of demittere, having the same meaning), of sovereignty and royal prerogatives to the late king or queen's successor without interregnum. By confusion, "demise" is sometimes interpreted as referring to the death of the Sovereign rather than to the transfer of the Crown. This erroneous meaning is undermined by the principle in constitutional law of the continuity of the monarchy, as expressed in the maxim "the Crown never dies".
