United States v. Pink, 315 U.S. 203 (1942), was a United States Supreme Court decision related to the Litvinov Assignment, wherein the US government recognised Soviet Russia as the successor of the previous Russian government.

The case concerned the return of over $1 million in assets held by the Superintendent of Insurance pursuant to the Litvinov Assignment.

The court stated that the action of New York amounted in substance to a rejection of a part of the policy underlying recognition by this nation of Soviet Russia.

Power over external affairs is not shared by the States; it is vested in the national government exclusively.The court ruled that rights to the property in question passed from the Soviet government to the United States by the Litvinov Assignment.
