"Through the Rain" is a song by American singer Mariah Carey, taken from her ninth studio album, Charmbracelet (2002). It was written by Carey and Lionel Cole, and produced by the former and Jimmy Jam and Terry Lewis. The song was released as the album's lead single on September 30, 2002, and a shorter version was used as the ending credits theme for a 2002 Japanese drama known as You're Under Arrest. Classified by Carey as a ballad, it is influenced by R&B and soul music genres, and features a simple and under-stated piano melody, backed by soft electronic synthesizers. "Through the Rain" was meant to be an insight into Carey personal struggles throughout 2001, and lyrically talks about encouraging others.

The song has been well-received, with many complimenting its inspirational lyrical content, and described it as an open window into Carey's personal life for listeners. Commercially, it was Carey's lowest-charting lead single on the US Billboard Hot 100 at the time, and it was her first lead single to that point not to reach the top ten in the United States. Though stalling at number 81, it became successful on the Billboard dance charts, hitting number one for a week in the United States as well as topping the Hot Singles Sales chart. The song achieved higher placements in international markets, reaching the top spot in Spain and peaking within the top ten in Canada, the Netherlands, Italy, Sweden, Switzerland and the United Kingdom.

Carey performed "Through the Rain" live on several television and award show appearances around the world. She debuted the song at the 2002 NRJ Awards, and features it on a one-hour special titled Mariah Carey: Shining Through the Rain, which aired three days later on MTV. In the United States, Carey performed the song on Today, The Oprah Winfrey Show, and American Music Awards of 2003. Throughout Europe, Carey performed the song on The Graham Norton Show and on talent competition, Fame Academy. Additionally, "Through the Rain" was included on the set-list of Carey's Charmbracelet World Tour: An Intimate Evening with Mariah Carey, which spanned throughout 2003–04.

The music video, directed by Dave Meyers, was set in the late 1960s. It features a past and present story-line based on Carey's childhood, and stars J. D. Williams and Jamie-Lynn Sigler as the singer's parents. The video begins with past scenes of Carey's mother being disowned by her family after becoming romantically involved with a black man, and finds the singer in the present walking through a heavy rainstorm in New York.
