Magnetic Hill Concert Site is a live music venue in Moncton, New Brunswick, Canada. It is one of the largest music venues in Canada. Originally built in 1984 for Pope John Paul II to hold a papal mass during his tour of Canada, the site was redesigned in the 1990s as a concert venue. The site has hosted annual or biennial summer concerts since the mid-2000s. Additional permanent infrastructure was installed following the 2005 concert headlined by The Rolling Stones. In 2011 a concert headlined by U2 saw the first use of the marketing term Magnetic Hill Music Festival.
