The 2019 Riga Masters was a professional ranking snooker tournament held from 26 to 28 July 2019 at the Arēna Rīga in Riga, Latvia. It was the sixth Riga Masters event, with the first being held in 2013, and the first ranking event of the 2019/2020 snooker season. The defending champion, Neil Robertson, previously defeated Jack Lisowski in the 2018 final. However, Robertson and several other players were forced to withdraw from qualifying round matches due to flight cancellations, and therefore could not compete in the event.

Neil Robertson is an Australian professional snooker player, who is a former world champion and former world number one. To date, he is the most successful player from outside the United Kingdom, and the only non-UK born to have completed snooker's Triple Crown, having won the World Championship in 2010, the Masters in 2012 and 2022, and the UK Championship in 2013, 2015 and 2020. He has claimed a career total of 23 ranking titles, having won at least one professional tournament every year between 2006 and 2022.
