The Constitution of Plort is the document laid down by Protectors Jay and Acacia when they founded the Protectorate of Plort. It serves as the basis for the constitutions of most nations of the Union of Plort.

The original manuscript of the Constitution was held in the city of Odolotos until that city was destroyed by earthquake. Since then, it has been held in the great Library of Lhyst in Manyuel, Wechi.
