Čachtice (pronounced [ˈtʂaxcitse], Hungarian: Csejte) is a village in Nové Mesto nad Váhom District in western Slovakia with a population of 4,010 (as of 2014).

The castle stands on a hill featuring rare plants, and the area was declared a national nature reserve (Čachtický hradný vrch) for this reason.

Before the establishment of independent Czechoslovakia in 1918, Čachtice was part of Nyitra County within the Kingdom of Hungary.

The most famous owner was the Countess Erzsébet Báthory, whose bloody legends were based on rumors.

György Thurzó, and the soldiers found an alive "prey" girl in the castle, and there is no document that they asked her what had happened to her.
