No. Jamaican citizens do not need a visa for tourist stays in Aruba up to 30 days, provided they hold a passport valid for at least six months beyond the date of entry.
Aruba is a constituent country of the Kingdom of the Netherlands. Its visa policy aligns with the Netherlands' Caribbean territories. Jamaicans also enjoy visa-free access to Curaçao, Sint Maarten, and the Caribbean Netherlands (Bonaire, Saba, St. Eustatius) under similar terms.
For stays beyond 30 days, or for work/study, a permit is required. Always confirm with the Aruba Tourism Authority or the nearest Dutch embassy/consulate before travel, as rules can change.
