Imperial Majesty (His/Her Imperial Majesty, abbreviated as HIM) is a style used by Emperors and Empresses. The style is used to distinguish the status of an emperor/empress from that of a king/queen, who are simply styled Majesty (HM).

Today the style has mainly fallen from use with the exception of the Emperor and Empress of Japan (in Japanese: 陛下, heika).
