The National Indian Gaming Commission (NIGC; /nɪɡˈsiː/) is a United States federal regulatory agency within the Department of the Interior. Congress established the agency pursuant to the Indian Gaming Regulatory Act in 1988. The commission is the only federal agency focused solely on the regulation of gambling, though it has many counterpart state and tribal regulatory agencies. The U.S. Department of Justice and the Department of the Interior also have responsibilities related to gaming and Indian gaming, respectively.
