The 1981 Benson & Hedges Masters was a professional non-ranking snooker tournament that took place from Tuesday 27 January to Sunday 1 February 1981 at the Wembley Conference Centre in London, England. The number of invited players had been raised to 12, which saw Steve Davis make his Masters debut and a rise in prize money. With the increase in the number of players the tournament was extended from 5 days to 6, with a Sunday finish.

Alex Higgins reached his fourth consecutive Masters final by defeating Cliff Thorburn 6–5 in the semi-finals, despite having trailed 1–5. There he reversed the result of the 1980 final against Terry Griffiths, who had himself made a dramatic recovery to beat John Spencer 6–5 in the semi-finals, after trailing 2–5 and needing two snookers in the eighth frame. Griffiths set a new tournament record break of 136 in the final. The tournament attracted 18,742 spectators in its six days, including a new British tournament record of 2,422 for the final session.
