Kahweol is a diterpenoid molecule found in the beans of Coffea arabica and is structurally related to cafestol. It was named after the Arabic قهوة qahwa meaning "coffee".

Kahweol belongs to a group of organic compounds known as naphthofurans, containing both naphthalene and furan moieties. It is a colourless crystal at room temperature that oxidises readily and yellows within hours.
