The Commerce Clause is an enumerated power listed in the United States Constitution (Article I, Section 8, Clause 3). The clause states that the United States Congress shall have power "To regulate Commerce with foreign Nations, and among the several States, and with the Indian Tribes". Courts and commentators have tended to discuss each of these three areas of commerce 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 a different application of the same sentence in the Constitution.
Dispute exists as to the range of powers granted to Congress by the Commerce Clause. As noted below, the clause is often paired with the Necessary and Proper Clause, the combination used to take a broad, expansive perspective of these powers. Many strict constructionists deny that this is the proper application of the Commerce Clause because it refers specifically to "the foreign Powers"
