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 2003, as well as songs which peaked in 2002 and 2004 but were in the top 40 in 2003. 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 sixty-four singles were in the top forty this year. Forty singles from 2002 remained in the top 40 for several weeks at the beginning of the year, or re-entered during the year. "Sk8er Boi" by Avril Lavigne" first charted in 2002 but reached its peak in 2003, while "Swing Low" by UB40 and the United Colours of Sound, "Hey Ya!" by Outkast and "Stunt 101" by G-Unit all charted in 2003 but reached their peak in 2004.

One-hundred and sixty-three artists had multiple entries in the top forty in 2003, with Big Brovaz, Blue, Christina Aguilera, Jay-Z, Justin Timberlake, Sean Paul and Shania Twain having the joint most entries (5). 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 2003, including songs that reached their peak in 2002 or 2004. 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 2003 having previously reached the top 40. The total number of weeks in the top 40 and re-entry dates are correct as of 27 December 2003 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).
