The 2019 WPA World Ten-ball Championship was a professional pool tournament for the discipline of ten-ball organised by the World Pool-Billiard Association (WPA) and CueSports International. It was the fifth WPA World Ten-ball Championship; the previous championship was held in 2015. After plans for an event in both 2016 and 2018 to be held in Manila fell through, a 2019 event at the Rio All-Suite Hotel & Casino in Las Vegas as part of a three-year deal for the event to be played in the United States was agreed. The event was held concurrently with the Billiard Congress of America's National Ten-ball event from July 22 to 26. The event was sponsored by cue manufacturer .
