"Suitcase" is a song by American recording artist Mary J. Blige. It was co-written by Mark J. Feist, Crystal Nicole, and Adrian Sotomayor, and produced by the former for Blige's soundtrack album Think Like a Man Too (2014), recorded for the comedy film of the same name. Sent as the album's lead and only single for urban contemporary and urban adult contemporary airplay in the US on June 10, 2014, following the release of the buzz track "A Night to Remember", it reached the top 30 on the US Adult R&B Songs chart.

On May 30, 2014, it was announced that Blige had recorded an entire collection of music from and inspired by Tim Story's comedy film Think Like a Man Too, the sequel to Story's 2012 film Think Like a Man based on Steve Harvey's book Act Like a Lady, Think Like a Man. Comprising 14 new recordings, including a remake of Shalamar's hit "A Night to Remember" as well as collaborations with musicians Jerry Duplessis, Rodney Jerkins and Pharrell Williams, Blige primarily worked with frequent contributors Tricky Stewart and The-Dream, who produced the bulk of the album.
