Pierre-Jean Garat (25 April 1764 – 1 March 1823) was a French Basque singer and nephew of Dominique Joseph Garat. He was born in Ustaritz. Garat devoted himself from an early age to the cultivation of his musical talents. Because he professed a distaste for the legal profession, which his father wished him to pursue, he was deprived of his allowance, but through the patronage of a friend he obtained the office of secretary to Comte d'Artois, and was afterwards engaged to give musical lessons to the queen of France. Garat died on 1 March 1823 in Paris.
