Béatrice Martin (born September 22, 1989), better known by her stage name Cœur de pirate (French: pirate heart) is a Canadian singer-songwriter. In a report broadcast on the French second public channel, she explained she "chose such a name not to appear as an isolated musician, but to get a band identity from the start. She started playing the piano when she was only three years old, and later, at the age of 15, she played as a keyboardist in the post-hardcore band December Strikes First which starred her best friend, Francis, who would later become the subject of one of the pieces of her debut album. After a brief stint as keyboardist for Bonjour Brumaire, she released her debut album Cœur de pirate in 2008 on Grosse Boîte. The album was subsequently nominated for Francophone Album of the Year at the 2009 Juno Awards. She attracted wider media attention in February 2009 when Francis Vachon, a photographer from Quebec City, used her song "Ensemble" as the soundtrack to a popular YouTube video depicting his baby son playing with toys, leading to coverage on Good Morning America.
