Sebastokrator (Medieval Greek: Σεβαστοκράτωρ, romanized: Sevastokrátor, lit. 'August Ruler', Byzantine Greek pronunciation: [sevastoˈkrator]; Bulgarian: севастократор, romanized: sevastokrator; Serbo-Croatian: sevastokrator), was a senior court title in the late Byzantine Empire. It was also used by other rulers whose states bordered the Empire or were within its sphere of influence (Bulgarian Empire, Serbian Empire). The word is a compound of sebastós (lit. 'venerable', the Greek equivalent of the Latin Augustus) and krátōr ('ruler', the same element as is found in autokrator, 'emperor'). The wife of a Sebastokrator was named sebastokratorissa (σεβαστοκρατόρισσα, sevastokratórissa) in Greek, sevastokratitsa (севастократица) in Bulgarian and sevastokratorica in Serbian.
