Antonio Giuglini (16 or 17 January 1825 – 12 October 1865) was an Italian operatic tenor. During the last eight years of his life, before he developed signs of mental instability, he earned renown as one of the leading stars of the operatic scene in London. He created several major roles for British audiences, appearing in the first London performances of Gounod's Faust and Verdi's Un ballo in maschera. In London, he was the usual stage partner of the great dramatic soprano Thérèse Tietjens.
