Do Brazil passport holders need a visa to visit ME?

No visa is required. Brazilian ordinary passport holders can enter Montenegro visa-free and stay for up to 90 days within any 180-day period for tourism or short visits. Brazil ordinary passport holders enjoy visa-free access to Montenegro for tourism and short visits. The official Government of Montenegro source confirms that nationals of Brazil "may enter, pass through the territory of and stay in Montenegro up to 90 days, with a valid travel document, without a visa." The 90-day allowance is counted within a 180-day period from the date of first entry. Montenegro is an EU candidate country whose visa policy mirrors Schengen rules, but it is NOT part of the Schengen Area or the EU, so the EU's ETIAS travel authorization does not apply to entering Montenegro, and Montenegro's 90-day count is separate from the Schengen 90/180 count. Travelers must hold a passport valid for the duration of the stay (six months beyond intended stay is recommended), carry proof of onward/return travel, and register their presence with the local police within 24 hours of arrival - hotels and licensed accommodation do this automatically. As of 2025, Montenegro has been tightening its visa policy to align with EU standards (removing visa-free access for some nationalities such as Armenia, Uzbekistan, Egypt and Kuwait in October 2025), but Brazil's visa-free status is unaffected.
