Pentaerythritol is an organic compound with the formula C(CH₂OH)₄. The molecular structure can be described as a neopentane with one hydrogen atom in each methyl group replaced by a hydroxyl (–OH) group. It is therefore a polyol, specifically a tetrol.

Pentaerythritol is a white solid. It is a building block for the synthesis and production of explosives, plastics, paints, appliances, cosmetics, and many other commercial products.

The word pentaerythritol is a blend of penta- in reference to its five carbon atoms and erythritol, which also possesses 4 alcohol groups.
