Nektarios Terpos (Aromanian: Nectar Tãrpo;^[1] Greek: Νεκτάριος Τέρπος; late 17th century–18th century) was an Orthodox Christian scholar and monk from Moscopole (today in Albania) of Aromanian ethnicity. He was the author of an important religious book, called A Handbook called Faith (Greek: Βιβλιάριο καλούμενον Πίστις), which was first published in 1732. Terpos, together with Cosmas of Aetolia, was one of the major contributors of religious and cultural revival under the Ottoman rule.^[2]

Terpos came from a wealthy family and spend his childhood in Moscopole.^[3] He was of Aromanian ethnic background.^[4][5] As a missionary he travelled in Epirus, covering vast areas from Arta to Berat.^[3] Terpos is also remembered for his work in the Ardenica Monastery where in 1731 he wrote a prayer in the form of a fresco. The prayer is in four languages (Albanian, Aromanian, Greek and Latin) and is the first writing in Albanian found in an Eastern Orthodox Church.^[6] It is also the oldest known text in the Aromanian language.^[7]

Persecuted, Terpo migrated to Italy, where in 1732 he published his main work named A Handbook called Faith (Greek: Βιβλιάριο καλούμενον Πίστις).^[8] The book was republished 12 times in less than a century (1732–1818).^[3] In the book Terpo chastises the Crypto-Christians of Albania, and invites them to never abandon the religion of their forefathers.^[9]
