Jean-Nicolas Servan, also known as Giovanni Niccolò Servando or Servandoni (2 May 1695 - 19 January 1766) was a French decorator, architect, scene painter and trompe-l'œil specialist.

He was the son of a carriage-builder at Lyon.

From 1724 to 1742 he was director of decorations at the Paris Opera, at that time situated in a wing of the Palais Royal. His activity was considerable, whether as a painter or as an inventor of scenic contrivances for fêtes at the marriage of royal personages.

He also designed the decorations for altars, and the façade for the church of Saint Sulpice in Paris. He died in Paris in the early 1766.

His writings include: Description abregée de l'eglise Saint Pierre de Rome (Paris, 1738) and La Relation de la répresentation de la forêt enchantée sur le théâtre des Tuileries, le 31 mars 1754.
