The Henley Passport Index is a global ranking of countries according to the travel freedom allowed by those countries' ordinary passports for their citizens. It was launched in 2005 as Henley & Partners Visa Restrictions Index and was updated to Henley Passport Index in January 2018.

The index annually ranks 199 passports of the world by the number of countries that their holders can travel to without requiring a visa. The number of countries that a specific passport can access becomes its visa-free "score". The data is obtained from the International Air Transport Association (IATA)'s Timatic documentation requirements database.
