Sangharaja (Pāli: sangha religious community + raja ruler, king, or prince) is the title given in many Theravada Buddhist countries to a senior monk who is the titular head either of a monastic fraternity (nikaya), or of the Sangha throughout the country. This term is often rendered in English as 'Patriarch' or 'Supreme Patriarch'.
