Sychyovsky District (Russian: Сычёвский райо́н) is an administrative[1] and municipal[3] district (raion), one of the twenty-five in Smolensk Oblast, Russia.

The area of the district is 1,803.90 square kilometers (696.49 sq mi).

[2] The western part of Sychyovsky District is a highland where sources of several rivers are located, including one of the Dnieper in the western tip of the district.

Northwestern tip of the district belongs to the Western Dvina (Daugava) basin, while the rest (mostly Sychyovka lowland) drains into the Volga via the Vazuza River; some territories were flooded when a reservoir was built.

In other words, Sychyovsky District is the eastern terminus of the Atlantic–Mediterranean watershed in Europe.
