An Armenian cross is a symbol that combines a cross with a floral postament or elements. The cross of Armenian Christianity is combined with the Christian cross, and this design was often used for high crosses (khachkar) – a free-standing cross made of stone and often richly decorated.

The Armenologist James R. Russell notes that the Armenian Cross incorporates influences from Armenia's Zoroastrian past. As Zoroastrian traditions were very much integrated into Armenian spiritual and material culture, they survived the zealotry of the Sasanian priest Kartir (fl. 3rd century) and his successors, and were ultimately incorporated into Armenian Christianity. Russell adds: "The Armenian Cross itself is supported on tongues of flame and has at its center not the body of Christ, but a sunburst".
