List of artists with the most UK singles chart number ones

The UK singles chart is a weekly record chart which for most of its history was based on single sales from Sunday to Saturday in the United Kingdom. The chart was founded in 1952 by Percy Dickins of New Musical Express (NME), who telephoned 20 record stores to ask what their top 10 highest-selling singles were. Dickins aggregated the results into a top 12 hit parade. NME's chart was published each week in its eponymous magazine. From 2003, music downloads became included in the chart, and rules were altered in 2006 so that singles could chart before physical formats were released. Since July 2014, it has incorporated music streaming service data, with music video views counted towards the chart from July 2018. From 10 July 2015, the chart has been based on a Friday to Thursday week.

This list shows the twenty-seven artists with the most number ones on the UK singles chart. American singer-actor Elvis Presley has most number one singles with twenty-one. English band The Beatles have the most number one singles for a band, with eighteen. American singer Madonna has the most number ones for a female solo artist with thirteen. English girl group the Spice Girls have the most number one singles for a girl group with nine.
