Discipline is the tenth studio album by American singer Janet Jackson. It was released on February 22, 2008, by Island Records. It is her only album released with the record label after her five-album deal with Virgin Records was fulfilled with the release of 20 Y.O. (2006). Jackson worked with producers such as Darkchild, Ne-Yo, Shea Taylor, Stargate, Johntá Austin, Jermaine Dupri, Tricky Stewart, and The-Dream on the album. Jackson's long-time producers Jimmy Jam and Terry Lewis did not contribute to the project. The album was executive produced by Island Urban president Dupri and Jackson. The album experimented with the electropop, house, and dance-pop genres and also contained R&B and hip hop-oriented tracks.

The album received generally positive reviews, with critics arguing that it was an improvement on Jackson's two previous albums. It debuted at number one on the US Billboard 200, becoming her sixth to top the chart, and her first number-one album since All for You (2001).
