John White Brownson (March 12, 1807 – September 5, 1860), was an American politician from New York.
He was born on March 12, 1807, in Sunderland, Bennington County, Vermont, the son of Dr. John White Brownson (1774–1824) and Laura (Chipman) Brownson (1782–1864), daughter of Chief Justice of Vermont Nathaniel Chipman (1752–1843).
In 1814, the family removed from Vermont to Gainesville, then in Genesee County, New York, where Dr. Brownson practiced medicine.
