"Style" is a song by American singer-songwriter Taylor Swift and is the third track from her fifth album, 1989 (2014). The song was written by Taylor Swift, Max Martin, Shellback, and Ali Payami. It was released to radio by Republic Records, in partnership with Swift's label Big Machine Records, on February 9, 2015, as the album's third single, following "Blank Space".

The song reached number 6 on the U.S. Billboard Hot 100 chart, becoming the third consecutive top-10 single from 1989 in the country, and entered the top-10 on charts of numerous regions, including Australia, Canada, and South Africa. It also made the top 40 in countries like the United Kingdom, Austria, Czech Republic, Hungary, Ireland, New Zealand, and the Netherlands. The accompanying music video was directed by Kyle Newman and premiered on February 13, 2015.

"Style" merely began as an instrumental track written by Ali Payami for himself and guitarist Niklas Ljungfelt. Ljungfelt, detailing the collaboration with Swift to the Grammys, stated that the track was not initially intended for anyone and he "didn’t have a clue that Taylor would sing on it." However, the collaboration with Swift was made possible when Payami played the track to Max Martin in his room at Wolf Cousins studio, with Swift becoming interested in the track after overhearing the beat through the door. After Payami agreed on the collaboration, Swift and Martin then proceeded to write new lyrics to the track.

"Style" debuted as a snippet in a Target commercial to promote her album. In late December 2014, Big Machine Records head Scott Borchetta answered a fan's question on an impromptu Q&A on social networking site Twitter. The fan asked, "What's Taylor's next single?," and Borchetta responded promptly that he was leaning towards "Style"—it was an "obvious single choice", according to Billboard. In January 2015, Republic Records officially announced "Style" as Swift's third single from 1989, set for a release of February 9, 2015. Swift explained the meaning and inspiration of the song to Ryan Seacrest during an interview on iHeartRadio in October 2014.
