; Romanian: Arhimandritul Averchie, also Averhie or Averkie; Aromanian: Arhimandrit Averchi; Greek: Αρχιμανδρίτης Αβέρκιος, romanized: Archimandrítis Avérkios), born Atanasie Iaciu Buda (Greek: Αθανάσιος Γιάτσου Μπούντας, romanized: Athanásios Giátsou Boúntas), was an Aromanian monk and schoolteacher.

Born in Avdella, he became hegumen and archimandrite in Mount Athos, where he was known as "Averchie the Vlach" (Greek: Αβέρκιος ο βλάχος, romanized: Avérkios o Vláchos).

[3] Atanasie's father was celnic Iani Iaciu Buda, who was mayor of Avdella during the times of Ali Pasha of Ioannina.

[2] Atanasie's nephew Ioan Șomu Tomescu was a teacher who wrote an account on the life of Averchie published in 1929 by the Aromanian historian Victor Papacostea.

[7] He is also recorded as having exclaimed Și eu hiu armân ("I am an Aromanian too") in 1862 during a military ceremony in Bucharest in Romania which emotionally moved him.

In 1865, 20,000 Romanian lei were allocated for the establishment of a boarding school in Bucharest for Aromanian children from the Ottoman Empire,[6] which functioned at the monastery of the Church of the Holy Apostles.

Romanian Aromanian biographer and essayist Sterie Diamandi stated that "we do not know to what extent this version corresponds to reality" and lamented the fact that the date and details of the death of a prominent figure like Averchie were not known.
