Spiritualized (stylised as Spiritualized®) are an English rock band formed in 1990 in Rugby, Warwickshire, by Jason Pierce (often known as J. Spaceman), formerly of Spacemen 3. After several line up-changes, in 1999, the band centred on Pierce (vocals, guitar), Doggen Foster (guitar) and Kevin Bales (drums and percussion) with revolving bassists and keyboard players. The band's current bassist, James Stelfox, has been playing with the band since 2012.

As of 2023, Spiritualized have released nine studio albums. The best known and most critically acclaimed of these is 1997's Ladies and Gentlemen We Are Floating in Space, which NME magazine named as their Album of the Year, beating other critically acclaimed albums by fellow British bands such as OK Computer by Radiohead and Urban Hymns by The Verve.
