Homoisocitric acid is an isomer of homocitric acid in which the hydroxyl is on the 2 position. {{Cite web | title=Homoisocitric Acid| url=https://pubchem.ncbi.nlm.nih.gov/compound/5119182|publisher=U.S. National Library of Medicine; National Center for Biotechnology Information}} It is an intermediate in the α-aminoadipate pathway of lysine biosynthesis where it is produced by homocitrate synthase and is a substrate for homoaconitase.

Homoisocitrate is an anion, salt, or ester of homoisocitric acid.
