Oblivion is a 1982 composition by Argentine tango composer and bandoneon player Astor Piazzolla. It appeared in the 1984 Italian film Henry IV but gained wider recognition later that year when performed and recorded by Italian singer Milva with French lyrics. It featuring a passionate, melancholic melody built on a slow milonga rhythm with jazz-influenced harmonies. Running three and a half minutes, it has been extensively arranged for various instruments and recorded by numerous classical and jazz artists.

Oblivion has been extensively arranged for various instrumental combinations. Common arrangements include versions for violin, cello, oboe and orchestra, string quartet, and numerous adaptations for solo instruments (e.g. piano, clarinet) with standard accompaniment such as symphonic or chamber orchestras. The piece's structural clarity and rhythmic foundation have made it particularly amenable to diverse instrumental interpretations. Cellist Yo-Yo Ma and pianist Kathryn Stott performed it in 2014 at London's Wigmore Hall. Among its notable classical recordings are those by violinist Joshua Bell and bandoneón player Carel Kraayenhof (2009), Charles Dutoit conducting the Montreal Symphony Orchestra with bandoneon player Daniel Binelli (2000), cellist Gautier Capuçon with the Paris Chamber Orchestra (2020).
