Design of a Decade: 1986–1996

Design of a Decade: 1986–1996 is the first greatest hits album by American singer Janet Jackson. It was released on October 2, 1995, by A&M Records. The album was issued through A&M as Jackson's contract with Virgin Records allotted her the option to leave the label following the release of her fifth studio album Janet (1993). The compilation features 14 of Jackson's singles from her three previous albums—Control (1986), Janet Jackson's Rhythm Nation 1814 (1989), and Janet—as well as two new tracks, "Runaway" and "Twenty Foreplay". The release of the collection was accompanied by a same-titled home video release.

Design of a Decade: 1986–1996 received positive reviews from music critics, who cited the number of hit singles on the record, but many noted its misleading title as the album's content predominantly spanned a five-year period. It was well received commercially, reaching number three on the US Billboard 200 and was certified double platinum by the Recording Industry Association of America (RIAA). The record also peaked inside the top ten in several countries worldwide, including Australia, Canada, Ireland, Japan, and the United Kingdom. Design of a Decade: 1986–1996 has sold more than ten million copies worldwide.
