Arnaldo Conti (Parma, 22 February 1855 — Milan, 24 March 1919) was an Italian conductor of opera. He spent much of his life on tour in opera houses around the world, directing performances with singers such as Adelina Patti, Luisa Tetrazzini, Marcella Sembrich, Emma Calvé, Fernando de Lucia, Riccardo Stracciari, Antonio Scotti and Jean and Edouard de Reszke. He seems not to have sought publicity; he rarely ventured into concert hall, or the recording studio unlike his younger, fellow Parma-born conductors, Cleofonte Campanini and Arturo Toscanini.
