Fleuriot de Langle was posthumously promoted to Chef de Division on 24 April 1788.
La Pérouse said of Langle that "He died for his humanity" and "I have lost by the most horrific of treasons my best friend, my friend for thirty years.
 A man full of spirit, judgement, knowledge, and certainly one of the best officers in all the fleets of Europe".
 His remains were buried in the choir of the church of Saint-Louis at Brest.

Paul-Antoine Fleuriot de Langle is featured on a Monument to the Dead on the site on the island of Tutuila in American Samoa, inscribed "Inauguré en 1883 pour honorer la mémoire de onze membres de l'expédition Lapérouse massacrés en ce lieu." (
inaugurated in 1883 to honour the memory of de Langle and the 11 other members of the Lapérouse expedition massacred on this site).

In 1999, an archaeological expedition to Vanikoro in 1999 dived on the wrecks of Boussole and Astrolabe, and found a silver fork with the coat of arms of Fleuriot de Langle.
