"Untouched" is a song by Australian duo the Veronicas, which is featured on their second studio album, Hook Me Up (2007).

The song was certified double platinum by Recording Industry Association of America (RIAA), selling over one million shipments there.

[1] An accompanying music video was released for the single, directed by Anthony Rose, where it was shot in Sydney, Australia.

Writing and recording of the song took place at Jessica and Lisa's home in Los Angeles, California.

[6] In an interview with Rachel Jones of Female First, Lisa explained the theme of "Untouched": "It's about not physically being able to touch someone or be with them but kind of needing that person".

[7] "Untouched" is an electropop and power pop song set in common time with an energy-filled fast tempo of 176 beats per minute.

[8] Ben Norman from About.com said "Untouched" is fast, both in BPM and in the way the twins vocally present the song, yet it proves once again that speed and pain are not mutually exclusive ideas.

"[10] K. Ross Hoffman from AllMusic had highlighted the track as an album standout, saying "'Untouched' bursts out of the gate with majestic, menacing string stabs and a driving synth-rock pulse beneath its stuttered verses and breathlessly obsessive refrain.

"[11] Emily Mackay from NME gave it a positive remark from the album review as she described the song as "raunchy".

[13] FemaleFirst.co.uk gave the song four-and-a-half out of five stars, saying "Other than that, this looks set to be an epic dance floor tune over the summer of 2009, it’s definitely finding a place on my iPod that’s for sure!".

[19] The single has since been certified 2× platinum by the Recording Industry Association of America, for sales of over two million units in the US.

After being previewed on BBC Radio 1 before release by Scott Mills, the song was playlisted on the station at "A-list", leading to "Untouched" debuting on the UK Singles Chart at number 92 for its first week.

[21] "Untouched" received an "MTV Push" and large amounts of airplay on music channels when it was officially released on 25 May 2009.
