Isabelle Boulay (born 6 July 1972 in Sainte-Félicité, Quebec) is a francophone Canadian pop singer. In 1990, some friends recorded her at the Petite-Vallée song festival without her consent, but she completed a performance there and was regarded as a huge success. The following year she won at the Granby song festival for her rendition of Jacques Brel's "Amsterdam". That same year she was invited to take part in the festival Les FrancoFolies de Montréal.
