"While Your Lips Are Still Red" is a 2007 song written by Tuomas Holopainen and Marco Hietala of the Finnish metal quintet Nightwish. It was performed by Holopainen, Hietala, and Jukka Nevalainen for the Finnish film Lieksa!, which was written and directed by renowned Finnish director Markku Pölönen; the film premiered in Finland in September 2007. The song is included on Nightwish's "Amaranth" single, which was released on 22 August 2007 as the second single of their sixth studio album, Dark Passion Play. It was also released on their live / compilation EP Made in Hong Kong (And in Various Other Places) in 2009.

"While Your Lips Are Still Red" is not an official Nightwish track, but Holopainen has stated that he is not comfortable with releasing any material under his own name. The Nightwish website clearly states that the song was written by Tuomas Holopainen and features him on keyboards, Marco Hietala on vocals and Jukka Nevalainen on drums. The song does not include guitars or female vocals. The videoclip accredits the song to Holopainen and Hietala, leaving out Nevalainen, who was not involved in the songwriting. The whispering in the background is done by Tuomas Holopainen.

The song has been played on concerts in various occasions, while guitarist Emppu Vuorinen and former vocalist Anette Olzon were backstage. More recent performances have also featured Floor Jansen with additional vocals, and Troy Donockley with a guitar solo played with an EBow in place of the prominent violin sound from the studio version. These include a performance at London's Wembley Arena in 2015 that was released on the band's 2016 live album Vehicle of Spirit.
