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. Until 2004 the chart was only 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 2004, as well as songs which peaked in 2003 and 2005 but were in the top 40 in 2004. 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).

Six-hundred and thirty-four singles were in the top forty this year. Forty singles from 2003 remained in the top 40 for several weeks at the beginning of the year, or re-entered during the year. "Hey Ya!" by Outkast, "Swing Low" by UB40 & United Colours of Sound and "Stunt 101" by G-Unit all first charted in 2003 but reached their peak in 2004. "Out of Touch" by Uniting Nations" and "Somebody Told Me" by The Killers both charted in 2004 but reached their peak in 2005.

Two-hundred and thirteen artists had multiple entries in the top forty in 2004, with Pete Doherty having the most entries (6), including singles as part of The Libertines and Babyshambles. Songs that reached the top ten this year are featured here but also included in their own article.

Entries by artist
The following table shows artists who achieved three or more top 40 entries in 2004, including songs that reached their peak in 2003 or 2005. The figures include both main artists and featured artists, while appearances on ensemble charity records are also counted for each artist.

Re-entries
This table shows singles that started a new chart run in 2004 having previously reached the top 40. The total number of weeks in the top 40 and re-entry dates are correct as of 25 December 2004 and does not include any weeks a song returned to the chart in subsequent years. The number of weeks next to the re-entry date may not be at the same position (i.e. a song could have risen or fallen from this placing).
