The Vuoksi (Russian: Вуокса; Finnish: Vuoksi; Swedish: Vuoksen) is a river running through the northernmost part of the Karelian Isthmus from Lake Saimaa in southeastern Finland to Lake Ladoga in northwestern Russia. The river enters Lake Ladoga in three branches, an older main northern branch at Priozersk (Käkisalmi), a smaller branch a few kilometres to the north of it, and a new southern branch entering 50 kilometres (31 mi) further southeast as Burnaya River (Finnish: Taipaleenjoki), which has become the main stream in terms of water discharge. Since 1857, the old northern distributaries drain only the lower reaches of the Vuoksi basin and are not fed by Lake Saimaa. The northern and southern branches actually belong to two separate river systems, which at times get isolated from each other in dry seasons.
The descent between Lake Saimaa and Lake Ladoga is 69 metres (226 ft). The entire run of the river is 162 kilometres (101 mi) via the Priozersk branch, or 150 kilometres (93 mi) via the Taipale branch. For most of its length, the river broadens out to a series of lakes bound together by shorter riverlike connections. One of these lakes, Uusijärvi close to Priozersk, was renamed Ozero Vuoksa ("Lake Vuoksa") by the Soviets.
The Vuoksi connects Lake Ladoga with central Finland, and was once an important route for trade and communication. A western branch, which disappeared due to ongoing land uplift, was an alternative route for the Karelians to reach the Gulf of Finland when the Neva River was blocked by enemies. Now the Saimaa Canal bypasses the Vuoksi and enters the Gulf of Finland in the Bay of Vyborg near the medieval city of Vyborg.
