"Too Close" is a song by British singer Alex Clare. The track was first released in the United Kingdom on 15 April 2011 as the second single from Clare's debut studio album, The Lateness of the Hour (2011). The track was written by Alex Clare and Jim Duguid and produced by Diplo and Switch (the collaborative members of reggae band Major Lazer), with co-production from Ariel Rechtshaid and Mike Spencer. Lyrically, the song describes the protagonist who is not ready for a committed relationship and he must end things with his love interest in good terms.

The song became popular after it was used in an advertising campaign for Microsoft's Internet Explorer 9. "Too Close" was a number-one hit in Germany and a top-ten hit in multiple countries, including the UK, where it peaked at number 4, and the U.S., where it peaked at number 7. The song has also been certified double platinum by the RIAA. The song was nominated for the Brit Award for Best British Single at the 2013 Brit Awards.

Clare said "Too Close" was inspired by a particular relationship with a close friend that turned romantic. He said, "One thing led to another, but it didn't really work out and that felt too close."

The song was first released in the UK on 15 April 2011 as the second single from the album. In March 2012, it was selected as the soundtrack to Microsoft's advertisement for Internet Explorer 9, released the following month. The exposure propelled the song to international success. This marked a turnaround in Clare's musical career and fortunes. Prior to it entering the UK Singles Chart, he had been forced to take a job as an estate agent after being dropped by his record label due to poor sales of his album. Soon after its success on the chart, Universal Republic Records signed Clare to a distribution deal that allowed The Lateness of the Hour to be released in the US.
