Hoke v. United States, 227 U.S. 308 (1913), was a decision by the United States Supreme Court that held that the United States Congress could not regulate prostitution per se, which was strictly the province of the states. Congress could, however, regulate interstate travel for purposes of prostitution or other "immoral purposes."
The case revolved around an offer to transport women from New Orleans to Beaumont, Texas for the purpose of prostitution. The Supreme Court upheld prosecution under the Mann Act.
