Pierre-Antoine Lebrun (; 29 November 1785 – 27 May 1873) was a French poet.
Biography
Lebrun was born in Paris. An Ode à la grande armée, mistaken at the time for the work of Écouchard Lebrun, attracted Napoleon's attention, and secured for the author a pension of 1200 francs. Lebrun's plays, once famous, are now forgotten. They are: Ulysse (1814), Marie Stuart (1820), which obtained a great success, and Le Cid d'Andalousie (1825).
Lebrun visited Greece in 1820, and on his return to Paris he published in 1822 an ode on the death of Napoleon, which cost him his pension. In 1825 he was the guest of Sir Walter Scott at Abbotsford. The coronation of Charles X in that year inspired the verses entitled La Vallée de Champrosay, which have, perhaps, done more to secure his fame than his more ambitious attempts.
