Čatež ob Savi (pronounced [ˈtʃaːtɛʃ ɔp ˈsaːʋi]; German: Tschatesch[2]) is a village on the right bank of the Sava River at its confluence with the Krka River in the Municipality of Brežice in eastern Slovenia.

Rejected derivations of the name include those from čata 'ambush' because of medieval transcriptions and linguistic geographical factors, and from Čatež (the name of a mythological dwarf).

[2] The parish church in the settlement is dedicated to Saint George (Slovene: sveti Jurij) and belongs to the Roman Catholic Diocese of Novo Mesto.

[6] A second church belonging to the parish is built on a hill to the south of the main village.

[7] A few kilometres to the east of the settlement is the large spa resort of Terme Čatež.
