"Luxurious" is a song by American singer and songwriter Gwen Stefani from her debut solo studio album, Love. Angel. Music. Baby. (2004). Written by Stefani and Tony Kanal, the track contains a sample of The Isley Brothers' 1983 song "Between the Sheets".

In addition to the Isley Brothers sample, the song features use of keyboards, synthesizers, and electric guitars. "Luxurious" is a contemporary R&B ballad whose lyrics describe the persona's desire to be rich in love, simultaneously comparing her lover with luxuries. The song also features Stefani's then-husband Gavin Rossdale who opens the song in French.

The song was released as the album's fifth single in October 2005 along with a remix featuring rapper Slim Thug. A music video was also released which featured Slim Thug, as well as the Harajuku Girls. The track received mixed reviews from critics, who generally found it less impressive than the previous singles. It charted within the top 40 in several countries, but had mediocre success overall and was less popular than the previous singles from Love. Angel. Music. Baby.

Stefani had an emotional breakdown from difficulties collaborating with many other artists and songwriters, so No Doubt bassist Tony Kanal invited her to his house. Kanal had been working on a track, which later became "Crash", the sixth single from the album. However, the two were unable to write anything following that, because they had differing ideas of how the music should sound. Stefani commented that "it was just frustrating and embarrassing to sit there and think we could write songs." Six months later, the two returned to work and came up with the beginnings of a song while working in Kanal's bedroom. The two experimented with combining various melodies and including what Stefani referred to as "this really kinda fast rappy part". This was the last song she and Kanal wrote together for the album.
