Do Brazil passport holders need a visa to visit MD?

No visa required. Brazilian ordinary passport holders can enter Moldova visa-free for tourism for up to 90 days within any 180-day period. Brazil is on Moldova's official visa-exemption list, confirmed by Moldova's Ministry of Foreign Affairs and the government eVisa portal. Brazilian ordinary passport holders may enter Moldova for tourism, business, or transit without a visa for up to 90 days in any rolling 180-day period. No advance application, eVisa, or visa-on-arrival is needed for this short stay. Moldova is NOT a member of the Schengen Area or the EU, so the Schengen 90/180 rule and the EU ETIAS travel authorization do NOT apply to entering Moldova itself; Moldova operates its own independent 90/180 visa-free regime. (ETIAS would only become relevant if a Brazilian traveler later continues onward to the Schengen Area, where Brazilians are also visa-free.) At the border, travelers should be prepared to show a passport valid for at least 3 months beyond the intended departure, proof of onward or return travel, accommodation details, and evidence of sufficient funds (a useful benchmark is roughly EUR 30 per day, and not less than EUR 300 for trips shorter than 10 days). Visa-free entry is not automatic admission - the final decision rests with border officers. Stays beyond 90 days, work, study, or residence require an appropriate Moldovan visa or permit.
