SDN48 (read "S.D.N. Forty-eight", short for Saturday Night 48) was a Japanese idol girl group, created and produced by Yasushi Akimoto. SDN48 was created based on an "adult idol" concept. Former AKB48 member Kayo Noro was chosen as the captain of the group. In November 2010, the group made their major label debut with "Gagaga". The group ended with a farewell concert on March 31, 2012.

In 2008, AKB48 producer Yasushi Akimoto decided to create a "Saturday Night 48" show, based on the concept of a "Adult idol" that would perform every Saturday at 10 pm. The shows were restricted to fans aged 18 and older. He also wanted to differentiate from AKB48's usual uniforms with sexier attire. In July 2009, two AKB48 members, Megumi Ohori and Kayo Noro were chosen as the first two members of the group. At the same time auditions were held to find other members. The SDN48 debut stage Yūwaku no Garter (誘惑のガーター Yūwaku no Gātā?, "Garter of Temptation") was held on July 25. At the end of AKB48's three-day Nippon Budokan concert the teams were reshuffled, leading to the removal of Kayo Noro, Megumi Ohori, Yukari Sato, and Kazumi Urano, leaving them to focus solely on SDN48 activities. Noro was also made the captain of the group.

It was announced on September 27, 2009, that understudy Yuki Iwata had departed from the group due to health reasons. Two months later, Eiko Maeda was transferred from sister group SKE48 to SDN48. Upon joining the group Maeda changed her stage name to Machiko Tezuka.

During their first year anniversary concert, Noro announced to the audience that SDN48 would debut under Universal Music in the fall. The group also suggested they would be eliminating the age restriction. Through their TV show, Suppon no Onna-tachi (すっぽんの女たち?), SDN48 held a senbatsu (選抜?, lit. selection) election to determine the top twelve members who would participate in their debut single. Former AKB48 member Megumi Ohori won No. 1 and was given the center position. The single would be titled "Gagaga" and be released on November 24, 2010. On September 30, 2nd generation member Sakura Fukuyama announced through her blog that she would be leaving the group due to health problems. Chinese member Chen Qu was chosen as Fukuyama replacement. The group was scheduled to release their second single "Ai, Juseyo" (愛、チュセヨ Ai, Chuseyo?, "Love, Give Me Please") on 23 March 2011; however, due to the Tōhoku earthquake and tsunami on 11 March, the single was postponed until 6 April.
