"Frozen" is a song by American singer and songwriter Madonna from her seventh studio album, Ray of Light (1998). Maverick and Warner Bros. Records released it as the album's lead single on January 23, 1998. The song was also included on the compilation albums, GHV2 (2001) and Celebration (2009). "Frozen" was written by Madonna and Patrick Leonard, who both produced it in collaboration with William Orbit. The mid-tempo electronica ballad, which has a layered sound enhanced by synthesizers and strings, lyrically addresses a cold and emotionless man.

"Frozen" received acclaim from music critics, some of whom deemed it as a highlight from Ray of Light. The song was described as being a masterpiece, and its melodic beat and sound were defined as "cinematic". "Frozen" was also a global commercial success. In the United States, it became Madonna's sixth single to peak at number two on the Billboard Hot 100. In the United Kingdom, "Frozen" became Madonna's first single to debut at number one on the UK Singles Chart, while also reaching number one in Finland, Greece, Hungary, Italy, Scotland and Spain, and the top-five elsewhere.

The accompanying music video for "Frozen", directed by Chris Cunningham, was filmed at Cuddeback Lake in California, and features Madonna as an ethereal, witch-like, melancholy persona, who shapeshifts into a flock of birds and a black dog. The music video won a Moonman for Best Special Effects in a Video at the 1998 MTV Video Music Awards. To promote Ray of Light, Madonna performed the song live in several occasions, including its first world premiere on Sanremo Music Festival in Italy and on Wetten, dass..? in Germany. Additionally, it was performed in several of her concert tours. "Frozen" has been covered by many artists, such as Swedish hard rock band Talisman, and Polish industrial metal band Thy Disease.

In 2021, a trap remix of "Frozen", made by Canadian DJ Sickick, became viral on TikTok. On December 3, 2021, it was officially released as the first single from Madonna's entire-catalog reissue project. Madonna and Sickick released three further renditions of the remix—the version featuring Nigerian singer Fireboy DML, the version featuring American rapper 070 Shake, and the version featuring vocals from Sickick himself titled "Frozen on Fire"—all of which were supported by music videos. The Sickick remix charted within the top-ten of the Billboard Dance/Electronic Songs chart, and was certified Gold by the Syndicat National de l'Édition Phonographique (SNEP) in France.
