List of UK Albums Chart number ones of the 1990s

The UK Albums Chart is a weekly record chart based on album sales from Sunday to Saturday in the United Kingdom; during the 1990s, a total of 216 albums reached number one. Until 1 February 1994, the chart was compiled each week by Gallup – after this date, it was managed by Millward Brown, who expanded the number of sales figures sampled, and extended the use of electronic point of sale machines. From July 1998 onwards, compilation of the chart was overseen by the Chart Information Network, jointly operated by the British Phonographic Industry (BPI) and the British Association of Record Dealers. Throughout the decade, the chart was based solely on physical album sales, and each week's number one was first announced on Sunday evenings on The Radio 1 Chart Show.
