多佛尔海峡（英语：Strait of Dover，法语：Pas-de-Calais）为英伦海峡最狭窄的地方，也译为加莱海峡。最短距离由南福兰（South Foreland）至格里内角（Cap Gris-Nez）。南福兰位于多佛尔东北6公里，格里内角位于加来的一个海岬。此两点为跨海峡泳客的最受欢迎路线，全长33公里。

多佛尔海峡在英伦海峡的东部地区，位于英伦海峡与北海的接触点。多佛尔海峡的阔度是英国与法国间最短的。晴朗的天气下可以用肉眼观望到对岸海岸线及沿岸建筑物。

The Strait of Dover or Dover Strait or historically Dover Narrows (French:Pas de Calais [pɑ d(ə)‿kalɛ], literally Strait of Calais, Dutch:Nauw van Calais [nʌu̯ vɑn kaːˈlɛː] or Straat van Dover) is the strait at the narrowest part of the English Channel, marking the boundary between the Channel and North Sea, separating Great Britain from continental Europe. The shortest distance across the strait is from the South Foreland, 33.1 kilometres (20.6 miles) northeast of Dover in the county of Kent, England, to Cap Gris Nez, a cape near to Calais in the French département of Pas-de-Calais, France. Between these points lies the most popular route for cross-channel swimmers.
