The coat of arms of Rhineland-Palatinate was, along with the flag of Rhineland-Palatinate, designed in 1947 after the new Land of Rheinland-Pfalz was formed by the authority of the French High Commissioner to Germany.

The coat of arms, an integral part of the state flag, symbolises the three predominant powers in the region before the French Revolution of the late 18th century: The Volkskrone (people's crown) consists of vine leaves and shows the importance of this crop for local agriculture.

§ 2 The state's coat of arms has the form of a round shield.

This is split by an ascending sagging peak and shows on the right side on a silver field a continuous red cross, on the left side red field a silver six spokes wheel and in the ascending black peak a redly crowned and reinforced, gold lion.

The coat of arms is covered by a golden people's crown (vine leaves)... § 4 Decisive for the design of the state's coat of arms and the state's flag are the patterns, added to this law.
