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.
