«Straight Up» is a 1988 hit single by American singer Paula Abdul, which reached number one on the Billboard Hot 100 and brought her widespread public attention. It was written and produced by Elliot Wolff.

The song is a mid-tempo dance tune. The synthetic lead trumpet sound comes from the Roland D-50 (preset 1-5). Daniel J. Levitin‘s This Is Your Brain On Music praises the song as «hold[ing] a certain appeal over many, many listenings».

«Straight Up» was the third single released from her debut album Forever Your Girl, after «Knocked Out» and «(It’s Just) The Way That You Love Me«. While the latter was enjoying success on the R&B charts, radio station KMEL in San Francisco started playing «Straight Up» from the album. The label decided to abandon «(It’s Just) The Way That You Love Me» and refocus its attention on «Straight Up». The strategy paid off, as «Straight Up» was followed by three more number-one hits from the same album.
