杰日尼奥夫角又称迭日涅夫角（俄语：Мыс Дежнёва），是楚科奇半岛上的海岬，其最东端位于北纬66° 4' 45"，西经169° 39' 7"，是整个欧亚大陆的最东端。杰日尼奥夫角北面是楚克奇海，南面是白令海，与阿拉斯加的威尔士王子角隔白令海峡相望。

由1648年首次发现它的俄罗斯航海家西姆仁·杰日尼奥夫所命名，现为俄罗斯楚科奇自治区管辖。在19世纪末到20世纪初，杰日尼奥夫角曾经是北美的鲸类和皮毛与楚科奇人贸易的中转站。

Cape Dezhnyov or Cape Dezhnev (Russian:мыс Дежнёва; formerly East Cape or Cape Vostochny) is a cape that forms the eastmost mainland point of Eurasia. It is located on the Chukchi Peninsula in the very thinly populated Chukotka Autonomous Okrug of Russia. This cape is located between the Bering Sea and the Chukchi Sea, 82 kilometres (51 mi) across from Cape Prince of Wales in Alaska; the Bering Strait lies between the two capes. The Diomede Islands and Fairway Rock are located in the midst of the strait.
