Knox Atoll is an unihabited coral atoll of 18 islands in the Pacific Ocean, and is the southernmost atoll of the Ratak Chain of the Marshall Islands. The total land area is only 0.98 square kilometres but it encloses a largely sand-filled lagoon with an area of 3.42 square kilometres. The atoll measures 11 kilometres in length and is 2 kilometres wide. The largest islets, located on the western and northern sides, include Aelingeo, Nadikdik and Nariktal. The atoll is connected by the Klee Passage to the southern point of Mili Atoll to which it was once connected.
