1-Octen-3-ol, octenol for short and also known as mushroom alcohol, is a chemical that attracts biting insects such as mosquitoes. It is contained in human breath and sweat, and it is believed that insect repellent DEET works by blocking the insects' octenol odorant receptors.

The name "mushroom alcohol" for 1-octen-3-ol comes from it first isolation by S. Murahashi in 1936 and 1938 from crushed matsutake mushrooms. A recent study on volatiles of this mushroom has shown this compound is only produced upon tissue disruption. This alcohol is found in many other mushrooms where it may play a role as an antifeedant.
