Jean-Baptiste Boyer-Fonfrède (1760 – 31 October 1793) was a French Girondin politician. A deputy to the National Convention from his native city, Bordeaux, he voted for the death of Louis XVI, denounced the September Massacres and accused Jean-Paul Marat. He was tried, condemned, and guillotined in Paris with the leading Girondin deputies on 31 October 1793. His son Henri Fonfrède (1788–1841) made his name as a publicist defending liberal ideas in Bordeaux's main newspaper under the Bourbon Restoration.
