The Ottawa Bluesfest is an annual outdoor music festival that takes place each July in downtown Ottawa, Ontario, Canada. While the festival’s lineup historically focused on blues music at its inception, it has increasingly showcased mainstream pop, hip hop, reggae, rock and EDM in recent years. Bluesfest has become the third largest music festival in Canada and the fourth largest music festival in North America.

The festival was first held in 1994 at Majors Hill Park with the performance of Clarence Clemons, attracting a 15,000 spectators. The following year the festival attracted larger crowds with entertainers like John Hiatt and Buddy Guy. In 1996, 250,000 fans attended the 10-day Bluesfest to see Robert Cray, Los Lobos and others.

Along with showcasing international musical talent, Bluesfest is a non-profit charitable organization with year-round music education initiatives such as Blues in the Schools, Be in the Band, and the Bluesfest School of Music and Art, augmenting a focus on developing local artists in the Ottawa region.
