DunkirkDunkirk (UKdʌnˈkɜːrk , USˈdʌnkɜːrk ; Dunkerque dœ̃kɛʁk) is a commune in the department of Nord in northern France. It lies from the Belgian border. It has the third-largest French harbour. The population of the commune in 2019 was 86,279. The name of Dunkirk derives from West Flemish dun(e) 'dune' or 'dun' and kerke 'church', thus 'church in the dunes'. A smaller town 25 km farther up the Flemish coast originally shared the same name, but was later renamed Oostduinkerke(n) in order to avoid confusion.
