Joseph Legros (7 September or 8 September 1739 – 20 December 1793) was a French singer and composer of the 18th century. He is best remembered for his association with the composer Christoph Willibald Gluck. Legros sang the role of Orpheus at the premiere of the 1774 version of Gluck's opera Orfeo ed Euridice and is usually regarded as the most prominent haute-contres of his generation, though his acting is reputed to have been mediocre.
