鳴門漩渦(日語:
鳴門の渦潮/なるとのうずしお Naruto no Uzushio)是發生在
日本鳴門海峽上的
漩渦景觀。
由於鳴門海峽最狹窄處寬度僅約1.4公里,中間的海底深度約90公尺,而其靠瀨戶內海一側的海底深度達200公尺,靠紀伊水道側則有深度約140公尺的海釜地形(小型的海底盆地)。由於海峽兩側的瀨戶內海和紀伊水道之間的潮位時間差,造成潮位差距最大時達1.5公尺,通過鳴門海峽的水流速度則會達到每小時20公里
[1],為日本國內潮流最快的地方,當快速的潮流與周圍流速較慢的海水接觸時便容易產生漩渦,漩渦最大時直接可超過20公尺。

鳴門的漩渦景觀可以搭乘觀光客船從海上近距離觀賞,也可自跨越鳴門海峽的
大鳴門橋內設置的
渦之道從其正上方約45公尺處直接俯瞰。
淡路島内3市等による「『鳴門のうず潮』世界自然遺産登録推進協議会」の発足(2012年10月)や南あわじ市と鳴門市による「『鳴門海峡の渦潮世界遺産化』推進交流会」の発足(2013年9月)など、
世界遺産登録を目指した取り組みが進められている

The strait between Naruto and Awaji island has a width of about 1.3 km (0.81 miles). The
strait is one of the connections between the
Pacific Ocean and the
Inland Sea, a body of water separating
Honshū and
Shikoku, two of the main islands of Japan. The tide moves large amounts of water into the Inland Sea twice per day and also removes large amounts of water twice a day. With a range of up to 1.7 m (5.6 ft), the
tide creates a difference in the water level of up to 1.5 m (4 ft 11 in) between the Inland Sea and the Pacific. Due to the narrowness of the strait, the water rushes through the Naruto channel at a speed of about 13–15 km/h (8–9 mph) four times a day, twice flowing in and twice flowing out. During a
spring tide, the speed of the water may reach 20 km/h (12 mph), creating
vortices up to 20 m (66 ft) in diameter.
The whirlpools can be observed from ships, or from the
Naruto Bridge spanning the strait. The suspension bridge has a total length of 1,629 m (5,344 ft), with the center span over the strait having a length of 876 m (2,874 ft) and a height of 41 m (135 ft) above sea level. A good view is also possible from the shore on Awaji island.
The whirlpools inspired the name for the manga character
Uzumaki Naruto from the manga
Naruto.
Uzumaki(うずまき) meaning whirlpool and Naruto referring to the bridge.
