Ireland Entry Requirements for US Travellers
Informational only — not insurance, financial, or medical advice. Coverage, exclusions, and limits vary by policy and insurer — read the full policy terms before buying. Entry rules can change; verify entry/visa rules and travel advisories on travel.state.gov (and passport-validity / entry requirements with the destination’s embassy) before you travel. Vaccination notes are generic CDC framing, not medical advice — check the CDC destination page and a clinician. Advisory level is as of 2026-06-12 and changes with events — verify the current level on travel.state.gov.
US citizens do not require a visa to enter Ireland for tourism or short-term visits. The US State Department maintains a Level 1 advisory for Ireland, indicating normal precautions apply. Your passport must be valid for the duration of your intended stay; verify current validity requirements on the State Department's Ireland country page. Proof of onward or return travel may be requested at check-in or upon arrival, so confirm documentation requirements with your airline and check the embassy website before departure.
No yellow fever vaccination is required to enter Ireland. There is no malaria risk in the country. The CDC recommends ensuring routine US vaccinations are current before travel, including vaccines for measles, mumps, rubella, tetanus, diphtheria, pertussis, polio, influenza, and COVID-19. For the most up-to-date vaccination guidance specific to your health profile, consult the CDC's Ireland destination page and speak with a healthcare provider before traveling.
