Enterodiol is an organic compound with the formula [HOC₆H₄CH₂CH(CH₂OH)]₂.

It is formed by the action of intestinal bacteria on lignan precursors. As such it is sometimes classified as a enterolignan or mammalian lignan. Elevated levels of enterodiol in urine are attributed consumption of tea and other lignan-rich foods.
