Anegada Passage is a strait in the Caribbean that separates the British Virgin Islands and the British ruled Sombrero Island of Anguilla, and connects the Caribbean and the Atlantic Ocean. It is 2300 m deep. Because the threshold depths are 1800 and 1600 m, Atlantic deep water from 1600 m level may flow into the deep areas in the Caribbean Sea.[1]

The Anegada Passage is a key shipping lane for the Panama Canal.[2] Often called the "Oh-my-god-a Passage",[3] it is considered a difficult passage for sailors because of the winds, waves, and swells.[4]

The passage consists of multiple basins and ridges. The Anegada Trough or Virgin Islands Basin was the likely site of the 1867 Virgin Islands earthquake and subsequent tsunami.[5][6]
