Yes, you can use a passport with your maiden name on a cruise, but only if the name on your cruise booking exactly matches the name on your passport. For most "Closed-Loop" cruises (trips that begin and end at the same U.S. port), the cruise line and U.S. Customs and Border Protection require that your legal identification matches your manifest. If your booking is in your married name but your passport is in your maiden name, you must carry a certified copy of your marriage license to act as a "linking document" to explain the name discrepancy. In 2026, many travelers find it simpler to book the entire cruise under their maiden name to avoid any administrative friction at the terminal. If you are flying internationally to join the cruise (e.g., a Mediterranean cruise), your airline ticket must also match the passport name exactly, or you will likely be denied boarding at the airport. It is always a "pro-tip" to ensure all travel documents—including insurance and shore excursion bookings—align with a single legal identity to prevent last-minute boarding delays or security issues.
