"Oh Mother" is a song recorded by American singer Christina Aguilera for her fifth studio album, Back to Basics (2006). The song was released on November 23, 2007 by RCA Records as the fourth and final single from the album in European territories, while "Slow Down Baby" was serviced as the final single in Oceania. It was written by Aguilera, Derryck Thornton, Mark Rankin, Liz Thornton, Christophe Barratier, Bruno Coulais and Kara DioGuardi. Production was done by Big Tank and Q, with L Boggie credited as co-producer and Aguilera serviced as additional producer.

"Oh Mother" is a downtempo pop and R&B piano ballad that talks about Aguilera's abusive childhood. It incorporates various musical instruments, from strings to keyboards. It contains a sample from "Vois Sur Ton Chemin", written by Bruno Coluais and Christopher Barratler. Upon its release, the song was met with mainly positive reviews from contemporary music critics. It also managed to enter charts in Europe with moderate success.

After releasing Stripped (2002) and collaborating with many different artists, Aguilera decided to record new old-school style materials for her upcoming album. She later explained that the lengthy break allowed her to write a lot about what she had experienced during that time. Aguilera also explained that she wanted to bring something novel to her album, which has 24 songs on it. She wanted to try to evolve as an artist and a visionary. As a result, Back to Basics, Aguilera's fifth studio album, is made up of two discs. On the first disc, she worked with "more beat-driven" producers, such as DJ Premier and Mark Ronson, who included samples in the production. The second one was written and produced solely by longtime producer Linda Perry. Aguilera sent letters to different producers that she hoped could help her with the direction she was taking for the project, encouraging them to experiment, re-invent and create a modern soul feel. She described the first disc as "kind of a throwback with elements of jazz, blues and soul music combined with a modern-day twist, like hard-hitting beats".
