"The Reason" is a song by Canadian singer Celine Dion, recorded for her fifth English-language studio album, Let's Talk About Love (1997).

Dion performed "The Reason" during her Let's Talk About Love Tour, and as a duet with Carole King on VH1 Divas and at the 48° Festival di Sanremo on 1998 in Italy.

Carole King recorded also her own version of this song for her 2001 album Love Makes the World, this time with Dion on backing vocals.

A reviewer from Music Week gave "The Reason" three out of five, stating that "Celine is back in classic power ballad territory here, though this track lacks the mega hooks of her previous hits.

"[2] The New York Observer editor Jonathan Bernstein reviewed, "It kicks off in time-honored fashion with a bombastic power ballad, "The Reason", co-written by Carole King and produced by Sir George Martin.

[3] Smash Hits gave it four out of five, writing, "'The Reason' starts off as you'd expect — all soft and lovely — then in come the strings and Celine steps up a gear.
