Article 1, Section 8, Clause 3 of the Unite States Constitution, known as the Commerce Clause, states that Congress has the exclusive authority to manage commerce between the states, with foreign nations, and Indian tribes. Courts and commentators have tended to discuss each of these three areas as a separate power granted to Congress. It is common to see the Commerce Clause referred to as "the Foreign Commerce Clause", "the Interstate Commerce Clause", and "the Indian Commerce Clause", each of which refers to the same single sentence in the constitution that covers all three.
