The UK Singles Chart is one of many music charts compiled by the Official Charts Company that calculates the best-selling singles of the week in the United Kingdom. Since 2004 the chart based on the sales of both physical singles with airplay figures excluded from the official chart.

This list shows singles that peaked in the Top 40 of the UK Singles Chart during 2009, as well as songs which peaked in 2008 and 2010 but were in the top 40 in 2009. The entry date is when the song appeared in the top 40 for the first time (week ending, as published by the Official Charts Company, which is six days after the chart is announced).

Three-hundred and fifty singles were in the top forty this year. One single from 2007 and forty-five singles from 2008 remained in the top 40 for several weeks at the beginning of the year, or re-entered during the year.

Additionally, "Thriller" by Michael Jackson re-entered the chart in 2008 and then returned to the chart in 2009 among a string of entries following Jackson's death.
