The Port of Lappeenranta (Finnish: Lappeenrannan satama, Swedish: Villmanstrands hamn) is an inland harbour in the city of Lappeenranta, Finland, on the southern shore of Lake Saimaa. It is located in the city centre on the Kaupunginlahti bay, and is therefore also known as the Kaupunginlahti harbour.
Scheduled international passenger services run from Lappeenranta to the Russian city of Vyborg (Finnish: Viipuri) on the Gulf of Finland, and wider afield, via the Saimaa Canal, which starts some 6.5 kilometres (4.0 mi; 3.5 nmi) east of the harbour. The total number of international passengers (departures and arrivals) was c. 16,400 in 2018.
