مضيق نارِس ( Nares Strait ؛ دنماركية: Nares Strædet; فرنسية: Détroit de Nares) هو ممر مائي بين جزيرة إلـِس‌مير وگرينلاند الذي يربط الجزء الشمالي من خليج بافن في المحيط الأطلسي مع بحر لنكون في المحيط الأطلسي. من الجنوب إلى الشمال، المضيق يضم Smith Sound, Kane Basin, قناك كندي, Hall Basin وقنال روبسون. ويوجد في مضيق نارس، بشكل شبه دائم، تيار من الشمال، تدفعه Beaufort Gyre، مما يجعل المرور فيه أكثر صعوبة للسفن القادمة من الجنوب.

Time-lapse imagery from July 9 to Sept. 13 2012 shows an ice island calve من Petermann Glacier and pass through Nares Strait.

In 1964, its name was agreed by the Danish (Stednavneudvalget, now Stednavnenævnet) and Canadian governments. The name derives from the British naval officer George Strong Nares.

The strait and neighbouring waters are usually hazardous for navigation and shipping. Icebergs and pack ice are present year-round; in an extreme example during 1962–64, a 20 km (12 mi) by 10 km (6.2 mi) ice island drifted southward from the Lincoln Sea through the Nares and Davis Straits to the Labrador Sea.[1] During August, however, it is usually navigable by icebreakers. Prior to 1948, only five vessels were recorded as having successfully navigated north of Kane Basin. In 2009 the ship Arctic Sunrise made the first known June transit into the Arctic Ocean.[2]

Hans Island, a tiny island lying within the strait, had been claimed by both Denmark (on behalf of Greenland) and Canada until an agreement on June 14, 2022 settled the dispute by drawing a border across it.[3] Other islands within the strait are Joe Island, Crozier Island, and the much larger Franklin Island.

Thule People reached the Nares Strait in the early 13th century, where they hunted with and traded with Vikings.[4] Archeological remains of Thule Culture and Viking presence are found on Ruin Island.
