The Preßnitz (Czech: Přísečnice or Přísečný potok) is a right-hand tributary of the River Zschopau in the state of Saxony in eastern Germany and in the Czech Republic. It rises in the Bohemian Ore Mountains near Horní Halže, northwest of the mining town of Měděnec.
The upper section of the Preßnitz, through the mining areas of Orpus (Mezilesí u Přisečnice) to its confluence with the Hammerbach stream (Hamerský potok) from Dörnsdorf (Dolina), was formerly known as the Hammerlebach.
Along the rest of the Preßnitz as it flows northwards are the old mining town of Přísečnice (German: Preßnitz), which was blown up in 1973 along with the neighbouring villages of Rusová (German: Reischdorf) and Dolina (German: Dörnsdorf), in order to dam the Preßnitz at that point and form a reservoir. In 1976 the Preßnitz Dam (vodní nádrž Přisečnice) was completed.
Above the town of Wolkenstein the Preßnitz finally discharges into the Zschopau.
Due to the iron ore deposits in the area there were many hammer mills along the Preßnitz in the past, for example in Schmalzgrube, Oberschmiedeberg, Mittelschmiedeberg und Niederschmiedeberg.
North of the dam on the border with Saxony is the village of Kryštofovy Hamry (German: Christophhammer), in which one of the seven factories that manufactured cobalt blue paint in Bohemia, the Blaufarbenwerk St. Christoph, was located until 1874.
From 1892 to 1986 the Pressnitz Valley Railway ran between Wolkenstein and Schmalzgrube, parallel to the Preßnitz River. After its closure a walking and cycling path was built between Wolkenstein and Steinbach on the old railway embankment along which the course of the river can be followed. Between 1995 and 2000 a museum railway was built between Steinbach and Schmalzgrube on the old embankment.
