Parallelograms is an album by American psychedelic folk singer Linda Perhacs.

Discouraged by the lack of commercial attention and the label's reluctance to promote the album, Perhacs returned to her career as a dental hygienist.

[7] Folk label the Wild Places reissued Parallelograms on CD and double LP in 2003.

Sunbeam Records again reissued the album in 2008, adding two bonus tracks, the previously unreleased 1978 song "I Would Rather Love" and an excerpt of a 2005 BBC interview.

Parallelograms was reissued again on vinyl by both Mexican Summer and Sundazed Music in 2010, and by Anthology Recordings in 2014.
