The 1966 Soviet submarine global circumnavigation (Russian: Подводная кругосветка советских атомоходов), was announced to be the second submerged around-the-world voyage executed by the detachment of the nuclear powered submarines that served in the Soviet Navy.^[1][2]

The expedition was an early example of blue-water operations and the power projection of the Soviet Union through its Navy's nuclear-powered submarine fleet, and it paved the way for future operations during the latter half of the Cold War. The Soviet expedition took place nearly six years after the first complete submerged circumnavigation of the world undertaken by the U.S. Navy's nuclear-powered submarine Triton in 1960.

Technically speaking, this Soviet submerged circumnavigation was not a true "circumnavigation" inasmuch as the submarine detachment went from the Soviet's Northern Fleet in the area of the Kola Peninsula to the Pacific Fleet base in Kamchatka going around South America, and hence had not gone completely around the world as had the USS Triton.
