Nicholas I or Nikolaj I was the Archbishop of Ohrid in 1346.
On Easter Day, 16 April 1346, the Serbian King Stefan Dušan convoked a huge assembly at Skopje, attended by the Serbian Archbishop Joanikije II, Nikolaj I, the Bulgarian Patriarch Simeon and various religious leaders of Mount Athos. The autocephalous Serbian Archbishopric was raised to the status of a Patriarchate. The new Patriarch Joanikije II now solemnly crowned Dušan as "Emperor and of Serbs and Romans (Greeks)".
