The Dardanelles (/dɑːrdəˈnɛlz/; Turkish: Çanakkale Boğazı, lit. 'Strait of Çanakkale', Greek: Δαρδανέλλια, romanized: Dardanéllia), also known as the Strait of Gallipoli from the Gallipoli peninsula or from Classical Antiquity as the Hellespont (/ˈhɛlɪspɒnt/; Classical Greek: Ἑλλήσποντος, romanized: Hellēspontos, lit. 'Sea of Helle'), is a narrow, natural strait and internationally significant waterway in northwestern Turkey that forms part of the continental boundary between Asia and Europe and separates Asian Turkey from European Turkey. Together with the Bosporus, the Dardanelles forms the Turkish Straits.
