Alfredo Kraus Trujillo (24 November 1927 – 10 September 1999) was a distinguished Spanish tenor from the Canary Islands (known professionally as Alfredo Kraus), particularly known for the artistry he brought to opera's bel canto roles. He was also considered an outstanding interpreter of the title role in Massenet's opera Werther, and especially of its famous aria, "Pourquoi me réveiller?" Kraus was born in Las Palmas de Gran Canaria.

His father was Austrian and his mother was Spanish. He began his musical career with piano lessons at the age of four, and he sang in the school choir by age eight. His older brother, Francisco Kraus Trujillo, a baritone, studied music and opera alongside him.
