Franz Gabriel Fiesinger or Flesinger (12 March 1723 – 21 February 1807) was a German engraver.
He was born in Offenburg and raised by Jesuits until the order was dissolved in 1773.
He spent the rest of his youth in Germany under the painter Franz S.
Stöber, before moving to Switzerland and then France, where he engraved portraits of members of the National Convention.
When the Reign of Terror broke out he moved to London, remaining there until 1798 and the birth of the French Consulate.
