The Montenegrin mafia (Crnogorska mafija) refers to the various criminal organizations based in Montenegro or composed of Montenegrins. There are 3700 documented organized criminals operating within Montenegro; outside of the country Montenegrin gangs are active throughout Europe-notably Serbia. The gangs tend to specialize in cigarette smuggling, narcotics and arms trafficking.
The Montenegrin police have just recently begun documenting and taking action against the many criminal gangs within Montenegro, discovering a vast network of powerful cartels and groups that play a central role in organized crime within the Balkans.
The Bar cartel
The organization are primarily involved in smuggling, arms trafficking, protection rackets and illegal gambling. The group are organized in the horizontal manner and higher-ranked members are not necessarily coordinated by any leader although lately the Bar mafia started regulating its vertical hierarchy making the organization much stronger. The organization has a local reputation to have connections with corrupt high-ranking men in Herceg Novi, Tivat, Kotor, Budva and Ulcinj Regional Police Units. 
Montenegrin mafia diaspora
With a large Montenegrin community, Serbia is host to many Montenegrin criminals and gangs. Operating mainly in the capital of Belgrade and Montenegrin enclaves in southern Serbia, these groups largely deal with the smuggling of narcotics and weapons. Some of these groups are also considered a part of Serbian Mafia. The issue is part of the controversy over ethnic and linguistic identity in Montenegro.
