The chemical compound neo-inositol is one of the nine stereoisomers cyclohexane-1,2,3,4,5,6-hexol, the "inositols".

Like the other stereoisomers, neo-inositol is considered a carbohydrate, specifically a sugar alcohol (to distinguish it from the more familiar ketose and aldose sugars, like glucose).

It occurs in nature, but only in small amounts; usually much smaller than those of myo-inositol, the most important stereoisomer.

The ring has the chair conformation with puckering parameter Q = 60.9 pm.

[9] Small amounts of neo-inositol can be deteceted in human urine.
