Aleksandrs Antoņenko (born 26 June 1975) is a Latvian tenor who specializes in the dramatic repertoire, and has appeared at the Metropolitan Opera and La Scala.

In 1998, he graduated from the Latvian Academy of Music, in the class of wind instruments, and in parallel began vocal lessons under Margarita Gruzdeva.

Aleksandrs Antoņenko won the Paul Sacher Prize in 2002, and then a Great Music award 2004 at home, in Latvia, for opera productions and a performance of the Verdi Requiem.

In 2011, Maestro Muti invited Antoņenko to perform Otello at the Opéra Garnier in Paris, accompanied by the Chicago Symphony Orchestra.

He continued his collaboration with the Swedish Royal Opera, where he took part in a new production of Puccini's La fanciulla del West.

The production was notable within American opera circles due to the Met's decision to abandon their tradition of blackface for the role of Otello.
