"From This Moment On" is a song by Canadian recording artist Shania Twain, taken from her third studio album, Come On Over (1997). The song was written by Twain, while additional production and songwriting was done by Robert John "Mutt" Lange. After finishing the track, both Twain and Lange concluded that the song would work best as a duet. Despite their first choice for the duet being Elton John, they chose country singer Bryan White instead, who took the opportunity. It was then released on March 14, 1998 in North America and Oceania.

"From This Moment On" is a country pop track which received generally favorable reviews from music critics, who deemed it as one of the album's highlights. The song achieved moderate commercial success, reaching the top ten in Australia, Canada, United Kingdom and United States. It also charted in France, Netherlands, New Zealand, and Sweden, as well on several Billboard component charts. An accompanying music video was directed by Paul Boyd, which depicts Twain walking down a hallway until she's joined by an orchestra to perform the song. "From This Moment On" has been performed on every tour by Twain since its release.

I'd never actually collaborated, as far as a duet, with anybody before, so it became a lot of fun. They let me do exactly what I wanted to do, and I think we blended real well together. I got to work out all kinds of different arrangement things with them."

"From This Moment On" was written during a soccer game in Italy. Twain once explained “We were in Italy at a soccer game. My husband loves sports. I don’t know the game that well, so my mind drifted and I started writing.” Initially, Twain thought "From This Moment On" would be perfect for singer Celine Dion; however, as Twain and Lange developed the song, they concluded that it would work best as a duet. Despite their first choice for the duet being Elton John, they chose country singer Bryan White instead, who took the opportunity. Twain later described White as "the best male voice in country music. Beyond country music! He's an excellent singer. So he needed to be on this record, because the song soars. It demands that. It demands dynamics." White explained that, by the time he went to the recording, the song was mostly finalized, and, vocally, described it as "extremely challenging."
