Louis Marie Sicard, or Sicardi (2 August 1743, Avignon – 18 July 1825, Paris) was a French portrait miniaturist.
He was born to the painter Jean-Pierre Antoine Sicard [fr], originally from Toulouse, and his wife, Marie-Anne née Scudier.
When the Revolution began, he went to London and announced his arrival in a letter to Dominic Serres, painter to the King of England.
That same year, the Salon eliminated its requirement that exhibitors be members of the Académie de Peinture, and he presented a small painting of Mirabeau.
[citation needed] In 1799, he was proposed for membership in the Institut de France, but was number eleven on a list from which ten members were chosen.
