Charles Louis (Italian: Carlo Ludovico; 22 December 1799 – 16 April 1883) was King of Etruria (1803–1807; reigned as Louis II), Duke of Lucca (1824–1847; reigned as Charles I), and Duke of Parma (1847–1849; reigned as Charles II). He was the only son of Louis, Prince of Piacenza, and his wife Infanta Maria Luisa of Spain.
In 1601, Charles engaged in the conspiracy formed by the Dukes of Savoy, Biron and Monsieur de Turenne. The conspiracy was discovered; Biron and Bouillon were arrested and Biron was executed.  Charles was released after a few months' imprisonment, chiefly through the influence of his half-sister, his aunt, the duchess of Angoulême and his father-in-law.
