The praepositus sacri cubiculi (Latin: "provost of the sacred bedchamber", in Greek: πραιπόσιτος τοῦ εὐσεβεστάτου κοιτῶνος, romanized: praipositos tou eusebestatou koitōnos) was one of the senior palace offices in the Late Roman Empire. Its holder was usually a eunuch, and acted as the grand chamberlain of the palace, wielding considerable authority and influence. In the 7th or 8th century, the title was also given to an order of rank for eunuch palace servants. The title and office continued in use in the simplified form of praipositos (πραιπόσιτος) in the Byzantine Empire until the late 11th century.
