The 1990 UK Championship (officially the 1990 StormSeal UK Championship) was a professional ranking snooker tournament that took place between 16 November and 2 December 1990 at the Guild Hall in Preston, England. This was the second and last UK Championship to be sponsored by StormSeal. The televised stages were shown on the BBC from 24 November to the final. Hendry beat 19-year-old fellow Scot Alan McManus in the semi-final by a 9–5 scoreline. McManus, who was in his rookie season, had just beaten Dennis Taylor, Steve Newbury, Silvino Francisco and Jimmy White to make the semis. Nigel Bond, who was a finalist at the Grand Prix a month earlier, made it to the quarter-finals losing to Davis. Defending champion Stephen Hendry defeated Steve Davis 16–15 in the final. The highest break of the tournament was 140 made by John Parrott.
