The Star of David (Hebrew: מָגֵן דָּוִד, romanized: Magen David, lit. 'Shield of David') is a generally recognized symbol of both Jewish identity and Judaism. Its shape is that of a hexagram: the compound of two equilateral triangles.

A derivation of the seal of Solomon, which was used for decorative and mystical purposes by Muslims and Kabbalistic Jews, its adoption as a distinctive symbol for the Jewish people and their religion dates back to 17th-century Prague. In the 19th century, the symbol began to be widely used among the Jewish communities of Eastern Europe, ultimately coming to be used to represent Jewish identity or religious beliefs. It became representative of Zionism after it was chosen as the central symbol for a Jewish national flag at the First Zionist Congress in 1897.

By the end of World War I, it had become an internationally accepted symbol for the Jewish people, being used on the gravestones of fallen Jewish soldiers.

Today, the star is used as the central symbol on the national flag of the State of Israel.
