Doclea or Dioclea, also known as Docleia or Diocleia was an ancient Illyrian, Roman and Byzantine city, in the region of the Docleatae tribe, now an archeological site near Podgorica in modern Montenegro.
It was an episcopal see since the late Roman period, and during the Early Middle Ages. Today, it is a titular see, both in the Eastern Orthodox Church, and in the Catholic Church.
When spelled as Diocleia or Diokleia, it should not be confused with ancient Phrygian city of Diokleia in Phrygia.
