Cannabinol (CBN) is a mildly psychoactive phytocannabinoid that acts as a low affinity partial agonist at the CB₁ and CB₂ receptors of the endocannabinoid system (ECS).

Although CBN shares the same mechanism of action as other phytocannabinoids such as tetrahydrocannabinol (THC), it has a lower affinity for CB₁ receptors, meaning that much higher doses of CBN are required in order to experience intoxicating effects.

It was the first cannabinoid to be isolated from plants of genus Cannabis and was discovered in 1896.
