Oklahoma State Constitution

The Constitution of the State of Oklahoma is the bedrock of our state's governance, guiding our laws and principles since its adoption in 1907. On November 16, 1907, Oklahoma became the 46th state to join the United States, ratifying both the U.S. Constitution and its own. At the time of its ratification, the Oklahoma Constitution was the longest governing document in the nation.

This living document has evolved with the state, with over 150 amendments approved by Oklahoma voters, reflecting the ongoing commitment to adapting and improving our governance.
