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 has been based on the sales of both physical singles and digital downloads, with airplay figures excluded from the official chart.

This list shows singles that peaked in the Top 40 of the UK Singles Chart during 2010, as well as songs which peaked in 2009 and 2011 but were in the top 40 in 2010. 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 seventy-three singles were in the top forty this year. Forty-nine singles from 2009 remained in the top 40 for several weeks at the beginning of the year, or re-entered during the year. "3 Words" by Cheryl Cole featuring will.i.am, "Broken Heels" by Alexandra Burke, "Don't Stop Believin'" by Journey, "Ego" by The Saturdays, "Look for Me" by Chipmunk featuring Talay Riley, "Playing with Fire" by N-Dubz featuring Mr Hudson, "Starstrukk" by 3OH!3 featuring Katy Perry, "Telephone" by Lady Gaga featuring Beyoncé, "The Climb" by Joe McElderry, "Tik Tok" by Kesha, "Young Forever" by Jay-Z featuring Mr Hudson and "You've Got the Love" by Florence and the Machine all first charted in 2009 but reached their peak in 2010.

Additionally, "All I Want for Christmas Is You" by Mariah Carey", "Fairytale of New York" by The Pogues featuring Kirsty MacColl and "Last Christmas" by Wham!" all returned to the chart at the end of 2009 and rose to a higher position during 2010, having peaked in previous years.

The list of singles that charted in 2010 but did not peak until 2011 include "Do It like a Dude" by Jessie J, "Girls" by N-Dubz, "Invincible" by Tinie Tempah featuring Kelly Rowland, "Lose My Mind by The Wanted, "More" by Usher, "What's My Name?" by Rihanna featuring Drake and "Who's That Chick?" by David Guetta featuring Rihanna.

Artists featured on the charity singles "Everybody Hurts" by Helping Haiti, "Heroes" by The X Factor Finalists 2010 and "You Are Not Alone" by The X Factor Finalists 2009 get an individual credit for these singles.
