Jean-Laurent Mosnier was a French painter and miniaturist.

Court painter under the Ancien Régime, Mosnier began, from 1789, a brilliant career as society painter in London, Hamburg and St. Petersburg. Many times academician, he left considerable work and high quality, both in miniature painting.

Self-Portrait with Two Pupils is thought to have been the basis for Jean-Laurent Mosnier's painting of himself with his young daughters. It is thought that his ambition was to clone the success of Adélaïde Labille-Guiard's painting.
