Atanasie Anghel Popa (died 19 August 1713) was a Romanian Greek-Catholic bishop of Gyulafehérvár (today Alba Iulia, Romania) between 1698 and 1713.

Large land holders began to persecute the new Romanian Greek-Catholic priests, a situation which Atanasie Anghel had to cope with.

The 54 protopopes, together with the priests and all the delegations present, signed a new act which reinforced the decision of the synod of 1698, reaffirming religious unification of Romanians in Transylvania with the Catholic Church.

For Greek-Catholic bishop Atanasie Anghel, there followed years of hardship, being attacked by Calvinists and also by the Orthodox Archdiocese of Bucharest.

[8] Anghel died in Gyulafehérvár on 19 August 1713, and was buried near the old church of the Bălgrad Metropolitanate (built by the ruler Michael the Brave).
