Pentaerythritol is an organic compound, a white, crystalline solid with the formula C₅H₁₂O₄. It is a polyol with the neopentane backbone and one hydroxyl group in each of the four terminal carbons. It is a building block for the synthesis and production of explosives, plastics, appliances, and many other important chemicals.

Pentaerythritol was first synthesized in 1891 by German chemist Bernhard Tollens and his student P. Wigand.

Pentaerythritol is a versatile building block for the preparation of many polyfunctionalized compounds, such as the explosive and vasodilator pentaerythritol tetranitrate (PETN) and the polymer cross-linking agent pentaerythritol tetraacrylate. Derivatives of pentaerythritol are components of alkyd resins, varnishes, polyvinyl chloride stabilizers, tall oil esters, and olefin antioxidants. Can be found in transformer oil, plastics, and many other applications.

Pentaerythritol is used to synthesize vasodilator pentaerythritol tetranitrate (PETN).
