The 1975 Masters (officially the 1975 Benson & Hedges Masters) was a professional snooker tournament that took place from 13 to 17 January 1975 at the West Centre Hotel in London. The inaugural edition of the Masters, it featured ten invited players.

John Spencer won the event, defeating Ray Reardon 9–8 on a re-spotted black in the final frame. The highest break of the tournament was 92, made by Spencer in the first frame of the final.

The snooker journalist Clive Everton managed squash player Jonah Barrington and because of this got to know the sports sponsorship consultants Peter West and Patrick Nally. Everton suggested to West and Nally that in their pitch to tobacco company Gallaher, they include a proposal to sponsor snooker tournaments. West and Nally won a contract with Gallaher that led to the company sponsoring events under its Park Drive brand: Park Drive 2000 events in 1971 and 1972 and the World Snooker Championship in 1973 and 1974. The 1975 World Championship was scheduled to be played in Australia and Park Drive exited from the sport, but another Gallaher brand, Benson & Hedges, institued the Masters for 1975. Ten leading professionals were invited, and the winner's prize of £2,000 was a record in the game. The tournament was held at the West Centre Hotel, London, which could accommodate 750 spectators.

Leonard Owen, director of special events for the sponsors, said that their ambition was to make the Masters the most stylish event in snooker, and to "recreate the atmosphere" of Leicester Square Hall. The chairman of the World Professional Billiards and Snooker Association, Rex Williams, who was one of the ten players invited to participate, commented that "The style and scope of this new event is a real boost for the game. It's what the professional players have been trying to achieve for some time." Ray Reardon, who was the world champion at the time of the event, later wrote that "Snooker's rise in social status was amply illustrated by a dinner jacket, champagne and smoked salmon setting for the Benson and Hedges Masters tournament".

The breakdown of prize money for the event is shown below:

First round matches were played on the 13 January. Bill Werbeniuk was whitewashed 5–0 by Alex Higgins. Werbeniuks cue had been stolen in December he was still not used to his new cue. He led by 31 points in frame two with one red remaining, but after losing this never appeared to be in contention to win.

Cliff Thorburn won the first three frames aginst John Pulman by comfortable margins. Pulman then took the next four frames, and in frame eight he fluked a snooker on the final blue ball; Thorburn failed to hit the blue and lost the frame and match.

The quarter-finals were played on the 14 and 15 January. Graham Miles took a 2–0 lead against Ray Reardon, who had defeated him in the final of the 1974 World Snooker Championship. Reardon levelled the match at 2–2, and Miles won frame five. Miles lost frame six when he went in-off the re-spotted black. Reardon took the next two frames, to lead for the first time at 4–3 and then win 5–3.
