Takk... ([ˈtʰaʰkː]) is the fourth studio album by the Icelandic post-rock band Sigur Rós, released in September 2005 on EMI. The album debuted at number 27 on the US Billboard 200, selling 30,000 copies in its first week. In 2006, Takk... was certified gold by the BPI, marking 100,000 copies sold in the UK. In total, it has sold over 800,000 copies worldwide. "Takk" means "thanks" in Icelandic.

Unlike its predecessor ( ), the album's lyrics are mostly in Icelandic, with occasional elements of Vonlenska ("Hopelandic"), a scat-like form of gibberish. The songs "Andvari", "Gong" and "Mílanó" are sung entirely in Vonlenska. Moreover, the song "Mílanó" was written together with the string quartet Amiina.

Rhythmically, Takk... makes extensive use of changing time signatures. In the track "Andvari" for example, the main melody repeats itself every 27 beats, with stress on beats 1, 5, 9, 11, 16, 20 and 25. This could be rendered as seven bars of 4, 4, 2, 5, 4, 5 and 3 beats respectively. Against this there is a steady counter-rhythm of triple time, which could be rendered as eighteen bars of 3/8 time per 27-beat cycle, also known as a phrase.

The first singles, "Glósóli" and "Sæglópur", were released on 15 and 16 August 2005 respectively, the former worldwide and the latter only in the United States. The single "Hoppípolla" was released in the UK on 28 November 2005 and entered the singles chart at No. 35 on 4 December. In May 2006 it reached No. 24 in the UK chart.

1,000 copies of Takk... on vinyl were manufactured and arrived in UK and US stores as of January 2006. It is composed of a gatefold sleeve housing two 12 inch records, with a single die cut page that houses a 10-inch record with a design etched on one side.
