Šaštín-Stráže (German: Schoßberg-Strascha, Hungarian: Sasvár–Morvaőr, Turkish: Şaşvar) is a town in the Senica District, Trnava Region in western Slovakia.

The name "Šaštín" consists of two parts: šáš (šašina, šáchor, present also in other Slavic languages – a sedge)[4] and týn (initially a fence, later also a small medieval fort).

Although the town's two parts, Šaštín and Stráže nad Myjavou were for long two separate villages, their history is closely connected to each other.

The villages merged in 1961 under name Šaštínske Stráže, changed in 1971 to the current name.

Several pilgrimages are held there annually, especially on Pentecost and Our Lady of Sorrows Day (15 September).
