In animal anatomy, the rhinencephalon is a part of the brain involved with olfaction.

Some references classify other areas of the brain related to perception of smell as rhinencephalon, but the areas of human brains that receive fibers strictly from the olfactory bulb are limited to those of the paleopallium. As such, the rhinencephalon includes the olfactory bulb, the olfactory tract, the olfactory tubercle and striae, the anterior olfactory nucleus and parts of the amygdala and the piriform cortex.
