No, as of 2026, you do not need a COVID-19 certificate, proof of vaccination, or a negative test result to enter Spain. All COVID-related travel restrictions for international arrivals were lifted in late 2022 and have not been reinstated. Travelers from all countries can enter Spain following standard immigration rules (such as having a valid passport and, for some nationalities, a Schengen visa). However, it is important to note that in 2026, visitors from visa-exempt countries (like the U.S., Canada, and the UK) must now apply for an ETIAS (European Travel Information and Authorisation System) authorization before traveling to Spain. While the COVID health forms are a thing of the past, the ETIAS is a new mandatory security requirement for entry into the Schengen Area. Always ensure your passport has at least three to six months of validity remaining beyond your intended date of departure to avoid any boarding issues at the airport.
