The Church of Saint Nicholas of the Lorrainers (Italian: San Nicola dei Lorenesi, French: Saint-Nicolas-des-Lorrains) is a Roman Catholic church dedicated to Saint Nicholas and the apostle Saint Andrew. It is one of the national churches in Rome dedicated to France (since the Duchy of Lorraine became part of France in 1766). Given to the Lorrainers by Pope Gregory XV in 1622, the pre-existing church of St. Nicholas was redesigned by Lorrainer architect François Desjardins (also called "Du Jardin" and italianized in "Francesco Giardini"), in 1632.
