Susan Magdalane Boyle (born 1 April 1961) is a Scottish singer who came to international attention when she appeared as a contestant on the TV programme Britain's Got Talent on 11 April 2009, singing "I Dreamed a Dream" from Les Misérables. Her first album was released in November 2009 and debuted as the number one best-selling album on charts around the globe.

Boyle's initial appearance on the talent show fired public imagination when her modest stage introduction left audience, viewers and judges alike unprepared for the power and expression of her mezzo-soprano voice. Before she had finished the song's opening phrase a standing ovation for Boyle had erupted. An international media and Internet response coincided. Within nine days of the audition, videos of Boyle—from the show, various interviews and her 1999 rendition of "Cry Me a River"—had been watched over 100 million times. She eventually finished in second place on the show behind dance troupe Diversity.
