Jean-Laurent Mosnier

Jean-Laurent Mosnier (; 1743 – 10 April 1808) was a French painter, active in Paris during the Ancien Régime's last decades and then in St. Petersburg during Tsar Alexander I's reign, best known for his portraits.

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 easel and miniature painting.

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