Nicodim (Romanian pronunciation: [nikoˈdim]), born Nicolae Munteanu ([nikoˈla.e munˈte̯anu]; 6 December 1864, Pipirig, Neamț County, Romania – 27 February 1948, Bucharest), was the head of the Romanian Orthodox Church (Patriarch of All Romania) between 1939 and 1948.

He studied theology at the Kiev-Mohyla Academy, Russian Empire and became a monk at Neamț Monastery in 1894. Nicodim was supportive of the Royal Family of Romania and a notable anti-Communist, refusing to give support for the Soviet-backed Communist regime in the process of installation in Romania in 1945–1947.^{[citation needed]} Immediately, rumors circulated to the effect that he had been murdered, perhaps with Soviet approval. However, all available evidence indicates the patriarch died of natural causes.^[1]

Nicodim Munteanu was buried at the Romanian Patriarchal Cathedral in Bucharest, next to the first Patriarch of Romania Miron Cristea.
