Romania is a secular state and has no state religion. However, an overwhelming majority of the country's citizens identify themselves as Christians. 86.7% of the country's population identified as Orthodox Christian according to the 2002 census, the vast majority of which belongs to the Romanian Orthodox Church. Other major Christian denominations include Protestantism (5.2%), Roman Catholicism (4.7%) and the Romanian Greek-Catholic Church (0.9%). The latter two religious organizations suffered most severely under the Communist regime.

Earlier still, the first known Daco-Roman Christian priest Montanus and his wife Maxima were drowned because of their Christian faith, as martyrs, on 26 March 304.
