The Zittau Mountains (German: Zittauer Gebirge, Czech: Žitavské hory; Upper Sorbian: Žitawske horiny), formerly also called the Lusatian Ridge (Lausitzer Kamm; Łužiski česak), refer to the German part of the Lusatian Mountains that straddle the Saxon-Bohemian border in the extreme southeast of the German state of Saxony.

The Zittau Mountains lie in the extreme south of the district of Görlitz in Saxony.

A few kilometres north of the range lie a number of settlements; from west to east they are Großschönau, Hainewalde, Olbersdorf, Bertsdorf-Hörnitz and Zittau.

In the mountains themselves are, again from west to east, the settlements of Waltersdorf, Oybin, Jonsdorf and Lückendorf .

The highlands are drained by streams that flow roughly north into the Mandau, a western tributary of the Lusatian Neisse.
