The 2017 Masters was a professional non-ranking snooker tournament that took place from 15 to 22 January 2017 at Alexandra Palace in London, England. It was the 43rd staging of the Masters and the second Triple Crown event of the 2016/17 snooker season, following the 2016 UK Championship and preceding the 2017 World Snooker Championship.

The Masters is a professional invitational snooker tournament. Held every year since 1975, it is the second-longest-running professional snooker tournament after the World Championship. It is one of the three Triple Crown events, along with the UK Championship and the World Championship. Although not a ranking event, it is regarded as one of the most prestigious tournaments on the World Snooker Tour. The reigning champion is Ronnie O'Sullivan, who won his eighth Masters title in 2024, defeating Ali Carter 10‍–‍7.
