'''Asam oleat''' atau asam ''Z''-Δ9-oktadekenoat merupakan [[asam lemak]] [[asam lemak tak jenuh|tak jenuh]] yang banyak dikandung dalam minyak [[zaitun]]. Selain minyak zaitun juga terdapat pada limbah industri sawit, yaitu lumpur sawit<ref>[http://repository.ipb.ac.id/handle/123456789/7663][Berbagai Usaha Memintas Rumenkan Asam Lemak Tak Jenuh]</ref> Asam ini tersusun dari 18 atom C dengan satu ikatan rangkap di antara atom C ke-9 dan ke-10. Selain dalam minyak zaitun (55-80%), asam lemak ini juga terkandung dalam minyak [[bunga matahari]] kultivar tertentu, minyak [[raps]], serta minyak biji anggur.
Rumus kimia: CH<sub>3</sub>(CH<sub>2</sub>)<sub>7</sub>CHCH(CH<sub>2</sub>)<sub>7</sub>)COOH.
Asam lemak ini pada suhu ruang berupa cairan kental dengan warna kuning pucat atau kuning kecokelatan. Asam ini memiliki aroma yang khas. Ia tidak larut dalam air, titik leburnya 15.3 °C dan titik didihnya 360 °C.
Asam oleat memberikan minyak zaitun karakteristik yang unik dan dalam bidang [[kuliner]] [[minyak zaitun]] menempati posisi "terhormat" di antara minyak-minyak masak yang lain.
Asupan asam oleat berlebih dapat menimbulkan [[steatosis]],<ref>{{en}} {{cite web
