Hanan Alattar is an American operatic soprano and actress who has had an active international career in concerts and in operas since the early 2000s. She has performed with many leading opera companies and orchestras in the United States and Europe, collaborating with such notable conductors as Plácido Domingo, James Conlon and Miguel Harth-Bedoya.
Alattar was born in Houston, Texas. She first became interested in opera while a student at Saint Agnes Academy in her native city. She studied vocal performance at the University of Texas at Austin and with Marlena Malas and Diane Richardson at the Juilliard School in New York City. While at Juilliard she portrayed roles in several productions, including Tatyana in Eugene Onegin, Lady Billows in Britten's Albert Herring, and the title role in Igor Stravinsky's The Nightingale (2004). In The New York Times review of the latter performance, Allan Kozinn wrote that "[Alattar] sang the Nightingale's music with beauty, suppleness and the right measure of flighty virtuosity."
Alattar was the New Horizon Scholar at the Aspen Music Festival from 2000–2002, and was notably the winner of the Aspen Concerto Competition in 2002. While at Aspen she performed the roles of Blanche in Edward Berkeley's production of Poulenc's Les dialogues des Carmélites under the baton of James Conlon, sang Giorgetta in Puccini's Il tabarro with conductor Julius Rudel, and performed the title role in Donizetti's Lucia di Lammermoor. In 2002–2003 she was a member of the Young Artist Program at the Opera Theatre of Saint Louis. She was a finalist in Houston Grand Opera's Eleanor McCollum Competition and in 2004 received the Sullivan Foundation Award.
