Mama is the debut studio EP by South Korean-Chinese boy band Exo-K and Exo-M, produced and released by S.M. Entertainment on April 9, 2012 in two language editions – Exo-K's Korean version and Exo-M's Mandarin version.

The EP was produced by Lee Soo-man, who is also the main producer for the group. The title for the EP is a Korean term used to address to a royal person, similar to the attributes "your highness" or "your majesty" in English. The title single "Mama" is written by Yoo Young-jin, who also co-wrote two other singles from the EP, "What Is Love" and "History".

From December 2011 to February 2012, S.M. Entertainment released twenty-three teaser trailers featuring the members of the group, which included some previews of the songs from the EP. The track "Angel" is used as background music in four teaser trailers. The track "Two Moons" is featured in Teaser #12, which starred Exo-K's Kai and Exo-M's Lay. "Machine" is featured in Teaser #5, starring Kai.

Exo-K promoted the title track "Mama" on music shows, along with track "History". They made their debut at music shows including SBS's Inkigayo, Mnet's M! Countdown, KBS's Music Bank and MBC's Show! Music Core from April 8 to April 15, while Exo-M performed at China's 12th Yinyue Fengyun Bang Awards that same day. Exo-K promoted the album by performing "Mama" on Korean music shows every week. EXO-M supported the album by being billed as the supporting artist on the Indonesian leg of Super Junior's Super Show 4 concert tour, and made consistent appearances on Chinese televised music programs and variety shows, including a guest appearance on an episode of Happy Camp.
