( ) is the third full-length album from Icelandic band Sigur Rós, first released in October 2002. It comprises eight untitled tracks, divided into two parts: the first four tracks are more light and optimistic, while the latter four are bleaker and more melancholic. The two halves are divided by a 36-second silence, and the album opens and closes with a click of distortion.

The album's title consists of two opposing parentheses; it has no other official title, though members of Sigur Rós usually refer to it in Icelandic as "Svigaplatan" ("The Bracket Album").

Fans have referred to it as "Parentheses" or "Brackets". A few call it "Vonlenska" due to the fact that the whole of the album is sung in that semi-language.

The album's vocals are recorded in "Vonlenska" ("Hopelandic"), which consists of meaningless syllables and resembles scat singing. The "language" is named after Von, the first song that featured it. Most of the syllable-strings sung by vocalist Jón Þór Birgisson are repeated many times throughout each song, and often throughout the whole album.

( ) was produced by Sigur Rós and engineered by Ken Thomas, who was also the engineer on Ágætis byrjun. On the majority of the album the band is accompanied by the string quartet Amiina, which is comprised of four young Icelandic women.
