Serbian–Montenegrin unionism

Serbian–Montenegrin unionism (Serbian: Српско-црногорски унионизам, romanized: Srpsko-crnogorski unionizam) is a socio-political movement which arose in the Balkans after the breakup of former Yugoslavia. It advocates Montenegro being in a political union with Serbia. The relationship between ethnic Serbs and Montenegrins is generally identified as being the most amicable of all the peoples of the former Yugoslavia.

According to a 2023 national census which enumerated a population of 623,633, some 32.9% or 205,370 Montenegrin citizens ethnically identified as "Serb", with 2,969 (<1%) identifying as "Serbian-Montenegrin" or "Montenegrin-Serbian".
