The Atlantic Bowls Championships was a lawn bowling competition held between national bowls organisations in the Atlantic region. The event was a qualifying event for the World Outdoor Bowls Championships until the 2021 announcement that it would no longer be held. Originally the Championships were for women only and were called the Atlantic Rim Championships. In 2007 men competed for the first time at the event. The 2001 tournament due to be held in Namibia was cancelled due to opposition from the Namibia Sports Commission. The next tournament was held in 2005.
