Coronado Exposition Commission Act of 1939

Coronado Exposition Commission Act of 1939 or United States Coronado Exposition Commission, 1939 is a United States statute establishing a federal exposition commission for national observance purposes. The commission provided representation of the United States by a commemoration and observance as related to the entrada of North America by Francisco Vázquez de Coronado in 1540. The commemorative exposition was a 400th anniversary regarding the exploration of the States of Arizona, Colorado, Kansas, New Mexico, Oklahoma, and Texas reasonably considering the Age of Discovery by the Spanish Empire's conquistadors.

The United States public law authorized the erection of a monument as stated in section five of the United States statute. The monument was to be located nearest the international boundary between the United States and Mexico where the Coronado expedition first crossed into modern day North America. The monument was established on August 18, 1941, as the Coronado International Memorial ― Coronado National Memorial ― located within the vicinity of Sierra Vista, Arizona.

The act of Congress was authored as House bill 6852 and Senate bill 2197. The S. 2197 legislation was passed by the 76th United States Congress and enacted into law by Franklin Roosevelt on July 17, 1939.
