"Chantaje" (Spanish pronunciation: [ʧanˈtaxe]; English: "Blackmail") is a song by Colombian singer-songwriter Shakira, featuring vocals by fellow Colombian singer Maluma. The song was released as a single to anticipate Shakira's upcoming eleventh studio album El Dorado (2017) on 28 October 2016 by Ace Entertainment. The song was written by Shakira, Maluma, Joel Antonio López Castro, Kevin Mauricio Jiménez Londoño and Bryan Snaider Lezcano Chaverra. It was produced by Shakira, Maluma, Chan "El Genio" (Rude Boyz) and Kevin Jiménez ADG. Maluma and Shakira previously collaborated on a remix of Carlos Vives' single "La Bicicleta".

"Chantaje" is a Latin pop and reggaeton song. Lyrically, the song was considered a "battle of the sexes", where the male protagonist is not sure where he stands with his lover, and the female protagonist does not exactly clear things up. The music video for "Chantaje" was filmed in Barcelona, Spain, with video director Jaume de Laiguana, Shakira's long-time collaborator. Commercially, the song topped the Spain, Chile, Mexico and US Billboard Latin Songs charts, while also reaching the top ten in Colombia, Argentina, Portugal and Switzerland.

Before collaborating with Shakira in "Chantaje", Maluma served guest vocals for the official remix of Carlos Vives and Shakira's 2016 song "La Bicicleta". Later, Maluma travelled to Barcelona in early September 2016 to work with Shakira, along with his production team. He confessed to Billboard that "he couldn't miss the opportunity to work with [her] again." The pairing was possible due to Sony Music, who proposed the idea for both artists working together again after the remix of "La Bicicleta". Maluma also commented about Shakira, stating: "It was an amazing experience. [...] She's a great artist, but she's also a composer. I learned a lot."
