"Matches" is a song recorded by American singer Britney Spears and American boy band Backstreet Boys for the deluxe reissue edition of Spears' ninth studio album, Glory (2016). It was written by Asia Whiteacre, Justin Tranter, and the song's producers Michael Wise and Ian Kirkpatrick. It is a dance, electropop, and glitch pop song consisting of the lyrics describing a dangerous relationship. The single met with positive reception, with critics pointing out the "90's vibe" that the song gives off.

"Matches" was initially intended for Backstreet Boys' ninth studio album DNA (2019), however it did not appear on the album. It was later repurposed to be a collaboration between Spears and the boy band. The track appears on the deluxe reissue of Glory, which was released on December 4, 2020. Additionally, Sony Music sent to radio airplay in Italy two weeks later, as the fifth and final single promoting the album. Commercially, it appeared at digital charts of Canada, Germany, the United Kingdom and the United States, peaking within top five on Malaysian RIM singles chart.
