"Hallelujah" is a song recorded by American country music singer Carrie Underwood and R&B singer John Legend, appearing on Underwood's first full-length Christmas album, My Gift (2020).^[1]

The song was written by Legend and Toby Gad, and sent to Underwood late into the album-making process.^[2] Underwood said, "I was deep into making the album, and this one kind of came in. He sent it to us kind of at the end. It was like, 'Well, I love the song. I feel like this is a puzzle piece I didn't know was missing, but now that I've heard it, I have to have it. And so we just put the ask back, 'Thank you for sending, do you want to sing a part with me, too?'."

"Hallelujah" received mostly positive reviews from music critics. Vinyl Chapters gave a positive review of the song, calling it a "breathtaking duet" between Underwood and Legend, and also a "notable standout track" from the album.^[3] The Washington Post highlighted the collaboration in its review of the album, writing, "These two Grammy winners push each other to new and impressive heights as they raise their voices to the heavens."^[4]

In the United States, "Hallelujah" reached number one on the Billboard Hot Christian Songs chart, becoming Underwood's third number one on that chart, and peaked at number three on both the Adult Contemporary chart and Hot Country Songs chart. It also peaked at number 54 on the Billboard Hot 100 chart.

The official music video premiered on November 19.^[5] It was directed by Randee St. Nicholas. It depicts Underwood in a snowy forest until she joins Legend at a piano inside an old, abandoned church. There are flashes of people in the background with candles, as they attended the church in its former glory. There are also two live doves on Legend's piano during the video.
