Bradish Johnson (April 22, 1811 – November 3, 1892) was an American industrialist and slave owner. He owned plantations and sugar refineries in Louisiana and a large distillery in New York City. In 1858 his distillery was at the heart of a scandal when an exposé in a weekly magazine accused it (and other distilleries) of producing altered and unsafe milk, called "swill milk", for sale to the public. The swill milk scandal helped to create the demand for consumer protection laws in the United States.
