The coat of arms of Serbia and Montenegro consisted of a shield with the Serbian eagle (a white double-headed eagle adopted from the Nemanjić dynasty) and the shield with a quartering the Serbian cross (or cross with firesteels) and the Montenegrin lion of Saint Mark (a lion passant adopted from the Republic of Venice).

This emblem had served as the national symbol of the State Union of Serbia and Montenegro (known as the Federal Republic of Yugoslavia until 2003).

Throughout history, the arms of both Montenegro and Serbia have featured a double-headed eagle, usually silver, on a shield, usually red, bearing on their chests usually a red shield, which in Montenegro's case contained a golden lion while in Serbia's a cross with four firesteels, usually silver.

The coat of arms was initially proposed by Aleksandar Palavestra of the Serbian Heraldry Society in 1992.

[1] The final, adopted version (designed by Bogdan Kršić) followed the same blason as the original proposal but differed in graphical style.
