Inni (Icelandic pronunciation: ​[ˈɪnːɪ], Within) is a live motion picture and album by Icelandic band Sigur Rós released in 2011. The concert footage was directed by Vincent Morisset and filmed at the Alexandra Palace in 2008. It was released on 7 November 2011 on various formats, including vinyl, DVD, Blu-ray and CD. Theatrical versions were shown around the world in late 2011.

It contains live tracks from all but one of the band's albums, and prominently features their (at-the-time most recent) album, Með suð í eyrum við spilum endalaust. Two tracks were released for free download off the band's website from the album, "Ný Batterí" and "Festival", and "E-Bow" was also made available for download with every pre-order of the package.
