Tetracosane, also called tetrakosane, is an alkane hydrocarbon with the structural formula H(CH₂)₂₄H. As with other alkanes, its name is derived from Greek for the number of carbon atoms, 24, in the molecule. It has 14,490,245 constitutional isomers,^[2] and 252,260,276 stereoisomers.^[3]

n-Tetracosane is found in mineral form, called evenkite, in the Evenki Region on Lower Tunguska River in Siberia and the Bucnik quarry near Konma in eastern Moravia, Czech Republic. Evenkite is found as colourless flakes and is reported to fluoresce yellow-orange.
