Thathanabaing, literally 'Keeper of the Sāsana', is the native Burmese rendition of Sangharaja, or formally Mahasangharaja (), which is typically rendered into English as 'Primate', 'Archbishop' or 'Supreme Patriarch.' The term "Sangharaja" was popularly used from the 1300s to 1400s, but lost currency in subsequent centuries. By the Konbaung dynasty, Thathanabaing and Thathanapyu (သာသနာပြု) were frequently used.
