Aquarius is an EP by Boards of Canada, released on 5 January 1998.

It is one of the shortest releases by Boards of Canada, barely breaking the 13-minute mark.

The track "Chinook" is a longer version of one that appeared on Boc Maxima, a publicly unreleased predecessor to Music Has the Right to Children.

The track contains a sample of "Aquarius" by Ren Woods as featured in the film version of Hair.

"Aquarius" was later covered by La Musique Populaire on their album A Century of Song.
