Pierre Lalo (6 September 1866 – 9 June 1943) was a French music critic and translator. He was the son of the composer Edouard Lalo. His reviews for the Parisian paper Le Temps combined conservatism and wit; among his principal targets was the composer Maurice Ravel, whose music Lalo disparaged throughout his career. In addition to his journalistic work Lalo served on the governing boards of the Paris Conservatoire and the national radio station Radiodiffusion.
