The village of Plyussa was first mentioned in the end of the 16th century. The name is derived from the Plyussa River. In the 19th century, it belonged to Luzhsky Uyezd of Saint Petersburg Governorate. Between 1851 and 1862, the railway connecting Saint Petersburg and Warsaw via Pskov was built and crossed Luzhsky Uyezd. This facilitated economic development of the eastern part of the current area of the district. The settlement of Plyussa was founded as a railway station in 1859, and later was merged with the village. Until 1923, Plyussa was a part of Kotorskaya Volost, and in 1923, Plyusskaya Volost, with the administrative center in the selo of Lyushchik, was established.
