John Bartow Prevost (March 6, 1766 – March 5, 1825) was an American attorney, judge, politician, businessman and diplomat. He became the first judge of the Superior Court of the Territory of Orleans from 1804–1808, and was U.S. political agent for Peru from 1818 until his death. Early life and family Prevost was born on March 6, 1766 in Paramus, New Jersey. His father Col. Jacques Marcus Prevost had emigrated from Geneva, Switzerland to Britain with his brother General Augustine Prevost, and rose in the British Army to command British forces in New Jersey and was briefly governor of Georgia during the American Revolutionary War before moving to the British West Indies to recover from his wounds and dying in Jamaica in 1779. His widow (and J.B. Prevost's mother), Theodosia Bartow, was a New Jersey native (only daughter of Theodore Bartow of Shrewsbury) and patriot during that war. In 1782, the widow married Aaron Burr. Burr (who would become Vice President of the United States under Thomas Jefferson) raised Theodosia's sons John and Frederick as his own. John B. Prevost married Frances Anna Smith, daughter of Rev. Samuel Smith, of Princeton College on February 5, 1799.

Prevost served alone on that bench from November 5, 1804, for about two years, due to the death and refusal to take office of his fellow judges. In 1808, Prevost resigned from the bench and was replaced by Joshua Lewis of Kentucky. Prevost remained in New Orleans and practiced law for several years. In 1818, President James Monroe appointed Prevost as American Commissioner to examine the state of Spanish colonies in South America. Secretary of State John Quincy Adams tasked Prevost to secure the Oregon Territory as reparations from the British government for the War of 1812 as spelled out in the Treaty of Ghent.
