"Oh Santa!" is a song by American singer and songwriter Mariah Carey from her second Christmas album and thirteenth studio album, Merry Christmas II You (2010). Carey wrote and produced the song in collaboration with Jermaine Dupri and Bryan-Michael Cox. It was released as the lead single from the album on October 1, 2010 by Island Def Jam Records. It is an up-tempo R&B song about Carey making a plea for Santa Claus to bring back her partner in time for the Christmas holidays. It received a positive response from music critics, with many praising its composition and style.

The track set a record on the United States Billboard Adult Contemporary songs chart, debuting at number twelve and peaking at number one the following week for four weeks. It became the first song to reach the summit in two weeks. It further became Carey's seventh number-one song on the chart. Carey filmed a 1960s-style music video to accompany the song's release as a single, and performed it on various programs in the lead up to Christmas, including her own TV special called Mariah Carey: Merry Christmas to You.

It was later adapted to be the finale of A Christmas Melody, a 2015 Hallmark Channel Christmas movie, with its lyrics tweaked to be relevant for Broadway child performer Fina Strazza's character singing about her single mother finding love. On December 4, 2020, a new version was released featuring singers Ariana Grande and Jennifer Hudson, as a single from the soundtrack to Mariah Carey's Magical Christmas Special for Apple TV+.

Critical reception

Mike Diver of the BBC wrote that "Oh Santa!" is a "boisterous" song which "makes perfect sense" as a lead single. He continued to write that although it fell substandard to "All I Want for Christmas Is You", it would still "warrant revisiting 12 months down the line". Rolling Stone writer Caryn Ganz commented on the composition, writing "Mariah bops to a schoolyard-chant beat". Joey Guerra of the Houston Chronicle described the song as "irresistible" and predicted that it would "dominate ringtones" in the run up to Christmas. A reviewer for Idolator described the track as a "boppy" Christmas version of Avril Lavigne's "Girlfriend". Rich Juzwiak of The Village Voice was critical of the song, writing "Of the four Mariah-penned new tracks, the Jermaine Dupri/Bryan-Michael Cox collaboration 'Oh Santa!' tries the hardest, an antique kitchen-sink replica that manages to invoke a cheerleading squad, the Pointer Sisters, Mariah's own 'Loverboy', and Hey Ya!'. Full of mumbling and cattiness, it's difficult to sing along to, so its prospects of becoming a perennial favorite are dim."
