Cyclopentanepentone, also known as leuconic acid, is a hypothetical organic compound with formula C₅O₅, the fivefold ketone of cyclopentane. It would be an oxide of carbon (an oxocarbon), indeed a pentamer of carbon monoxide.

As of 2000, the compound had yet to be synthesized in bulk, but there have been reports of trace synthesis.

Cyclopentanepentone can be viewed as the neutral counterpart of the croconate anion C₅O₅²⁻.

The compound referred to in the literature and trade as "cyclopentanepentone pentahydrate" (C₅O₅·5H₂O) is probably decahydroxycyclopentane (C₅(OH)₁₀).
