"Chanchullo" (Spanish pronunciation: [tʃanˈtʃuʝo]; literally: "scam", "racket", "hustle") is a danzón-mambo composed by Cuban bassist Israel "Cachao" López.

It was the third single released on Cuban independent record label Gema and has been covered by multiple artists including Tito Puente, Típica '73 and Rubén González.

The first recording of "Chanchullo" was made in 1949 for RCA Victor by Julio Gutiérrez's orchestra under the title "Mambolandia" and credited to Peruchín, who plays piano on the track.
