Shaker Loops is a 1978 composition by American composer John Adams, originally written for string septet. The original "modular" score, published by Associated Music Publisher, has since been withdrawn and replaced by a 1983 string orchestra version. This version was first performed in April of that year at Alice Tully Hall, New York, by the American Composers Orchestra, conducted by Michael Tilson Thomas. The string orchestra version can be played either by a septet of soloists or by a string orchestra of any size, where the violins are divided into 3 parts throughout.

The work is in four movements.
