Lebyazhye (Russian: Лебя́жье; Finnish: Lepäsi) is an urban locality (an urban-type settlement) in Lomonosovsky District of Leningrad Oblast, Russia, located on the coast of the Gulf of Finland 25 kilometers (16 mi) west of Lomonosov and 30 kilometers (19 mi) east of Sosnovy Bor.

[10][11] A variant of the current name first appears in 1504/1505 in reference to the nearby Lebyazhya river, likely being a translation of an original Ingrian Joutsenoja, with joutsen and лебедь both meaning "swan".

In 1864, the railway was open, and in the 1860s, Lebyazhye started to specialize as a settlement for maritime pilots who brought the ships to Saint Petersburg.

The fort played a key part in the Siege of Leningrad as the center of the Oranienbaum Bridgehead during World War II.

In the beginning of the 20th century, Lebyazhye was a part of Petergofsky Uyezds of Saint Petersburg Governorate, with the center in Petergof.

Between August 1941 and January 1944, during World War II, Lebyazhye was a part of the Oranienbaum Bridgehead, which was protecting the city of Saint Petersburg.

In order to visit the zone, a permit issued by the local Federal Security Service department is required.
