"Oh Mother" is the fourth single from Christina Aguilera's third studio album, Back to Basics (2006). The single—penned by Christina Aguilera, Derryck Thornton, Mark Rankin, Liz Thornton, and Kara DioGuardi—was released as an international double A-side with "Slow Down Baby".

The single was delivered to the European region as "Oh Mother", while the Oceanian and Asian regions of the world received "Slow Down Baby" earlier that year on July 28, 2007. It was not released in the United States.

The release was set on November 23, 2007 in Germany and Austria. In Switzerland, the single charted for four weeks based solely on downloads. On December 8, 2007 it was added to the A-Playlist of BBC Radio 2 in the United Kingdom and was released as digital download on December 31, 2007. On the German Airplay Chart, the song peaked at number four, while on the Austrian one at number eleven.

Promotional singles were sent out in July 2007, however heavy rotation did not pick up till around autumn 2007. Some promo singles were misprinted listing "Oh Mother" with a radio edit when in fact it was the album version. However, for the video release, Aguilera used a live recording for the music video and concert footage. The video version runs almost a minute longer than the actual album version.

The song was written about Aguilera's mother's abusive relationship with her husband. The single contains elements of the song "Vois Sur Ton Chemin" written by Bruno Coulais, which appeared in the 2004 film The Chorus. It was produced by Big Tank, L Boogie, and Aguilera herself.
