The High Synagogue, also called the Vysoká Synagogue (Vysoká means High in Czech), the official name in Czech: Vysoká synagoga, also known under its German synonym die Hohesynagoge, or as בה"כ גבוה Bet HaKnesset Gvuah in Hebrew or הויכשול Hoykhshil in Yiddish, is a Jewish congregation and synagogue, located on Červená ulice (Red Street), Prague, in the Czech Republic.

The synagogue building served as the meeting place for the rabbinical court and the Jewish council.

The interior lunette vaults with decorative stucco work remained in their original Renaissance style.

The congregation worshiped in this location until the autumn of 1941, and then used as a warehouse during German occupation and Czech communist rule.

In 1994 - 1996 the synagogue was restored and since 1997, it has again served the purposes of the Prague Jewish community’s chapel after a pause of nearly fifty years.
