Decene {{IPAc-en|d|ɛ|k|iː|n}} is an organic compound with the chemical formula {{chem2|C10H20}}. Decene contains a chain of ten carbon atoms with one double bond, making it an alkene. There are many isomers of decene depending on the position and geometry of the double bond. Dec-1-ene is the only isomer of industrial importance. As an alpha olefin, it is used as a comonomer in copolymers and is an intermediate in the production of epoxides, amines, oxo alcohols, synthetic lubricants, synthetic fatty acids and alkylated aromatics.http://www.ineosoligomers.com/media/files/lao/LAO%20C10%20Data%20Sheet.pdf 1-Decene (Alpha Olefin C10)], ineosoligomers.com

The industrial processes used in the production of dec-1-ene are oligomerization of ethylene by the Ziegler process or by the cracking of petrochemical waxes.[http://www.inchem.org/documents/sids/sids/AOalfaolefins.pdf Alfa Olefins] {{Webarchive|url=https://web.archive.org/web/20170517120901/http://www.inchem.org/documents/sids/sids/AOalfaolefins.pdf |date=2017-05-17 }}, SIDS Initial Assessment Report

Dec-1-ene has been isolated from the leaves and rhizome of the plant Farfugium japonicum and has been detected as the initial product in the microbial degradation of n-decane.
