John Higgins is a Scottish professional snooker player. He has won 31 ranking titles, placing him in third position on the all-time list of ranking event winners, behind Ronnie O'Sullivan (41) and Stephen Hendry (36). Since turning professional in 1992, he has won four World Championships, three UK Championships and two Masters titles, for a total of nine Triple Crown titles; this puts him behind only O'Sullivan (23), Hendry (18) and Steve Davis (15), and level with Mark Selby. A prolific break-builder, Higgins has compiled over 900 century breaks in professional competition, including 13 maximum breaks, second only to O'Sullivan's 15. He is also the oldest player to make a maximum break in professional competition, having set the record at the 2024 Championship League when he was aged 48 years and 268 days. He has reached the world number one ranking position four times. Alongside O'Sullivan and Mark Williams, he is one of the three players known as the "Class of '92", who all turned professional during the 1992–93 snooker season.

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.
