The 1983 World Snooker Championship was a professional snooker tournament that took place between 16 April and 2 May 1983 at the Crucible Theatre in Sheffield, England. This was the third and final world ranking event of the 1982–83 snooker season following the 1982 Professional Players Tournament. Sixteen seeded players qualified directly for the event, with an additional sixteen players progressing through a two-round qualification round held at the Romiley Forum in Stockport, and Redwood Lodge in Bristol. The winner of the event received £30,000, and the tournament was sponsored by cigarette company Embassy.

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.
