"A Moment Like This" is the debut single by American singer Kelly Clarkson, the winner of the first season of American Idol. It was released as a double-A side with "Before Your Love" and topped the Billboard Hot 100. The song was later included on her debut album, Thankful (2003). It is her coronation song from American Idol.

In 2006, the song was recorded and released by British singer Leona Lewis, the winner of the third series of The X Factor. Her version gained the Christmas number one, outselling the rest of the top 40 combined. Lewis' version has sold 914,000 copies as of 2015.

The song was co-written by Jörgen Elofsson and John Reid (of dance act Nightcrawlers) and produced by Stephen Ferrera and Steve Mac. It was written to be the first single for the winner of the first season of American Idol. As a result, the four remaining finalists, Kelly Clarkson, Justin Guarini, Nikki McKibbin, and Tamyra Gray each recorded a version of the song in case he or she won. The song was first revealed to the public when Guarini and Clarkson competed in a final showdown while singing this song, along with another track, "Before Your Love". After the American public had voted, Guarini performed the song (and Clarkson performed "Before Your Love") at the final show before the results were revealed. When Clarkson was announced as the winner, she became emotional, and sang the song as her final performance.
