The 2017 World Snooker Championship was a professional snooker tournament that took place from 15 April to 1 May 2017 at the Crucible Theatre in Sheffield, England. It was the 19th and final ranking event of the 2016–17 season which followed the China Open. It was the 41st consecutive year that the World Snooker Championship had been held at the Crucible.

Snooker is a cue sport played on a rectangular billiards table covered with a green cloth called baize, with six pockets, one at each corner and one in the middle of each long side. First played by British Army officers stationed in India in the second half of the 19th century, the game is played with twenty-two balls, comprising a white cue ball, fifteen red balls, and six other balls—a yellow, green, brown, blue, pink, and black—collectively called the colours. Using a cue stick, the individual players or teams take turns to strike the cue ball to pot other balls in a predefined sequence, accumulating points for each successful pot and for each time the opposing player or team commits a foul. An individual frame of snooker is won by the player who has scored the most points. A snooker match ends when a player reaches a predetermined number of frames.
