The 1993 Royal Liver Assurance UK Championship was a professional ranking snooker tournament that took place at the Guild Hall in Preston, England. The event started on 12 November 1993, and the televised stages were shown on BBC between 20 and 28 November 1993. The highest break of the tournament was a 141 made by David Roe. Ronnie O'Sullivan became the youngest winner of a ranking event at the age of 17 years and 358 days by defeating Stephen Hendry 10–6 in the final; as of 2021 this record still stands. This was the first of O'Sullivan's record seven titles at the tournament.
