Mükemmel (Perfect) is the eleventh studio album by Turkish singer Hande Yener. It was released on 2 June 2014 by Poll Production. After working with Sinan Akçıl on her three previous studio albums, Yener ended her friendship with Akçıl and after it became evident that the two would not work together on any projects again, in May 2013 she released the new single "Ya Ya Ya Ya", which was written by Berksan. Following the single's release, she began working on her new studio album, and after years she took new songs from Altan Çetin with whom she had worked on a number of her early albums. Alongside Çetin, Mert Ekren and Volga Tamöz joined the album's personnel as songwriters.
