In anatomy of animals, the archipallium is the oldest region of the brain's pallium.
The archipallium is often considered contiguous with the olfactory cortex, but the extent of the archipallium varies among species. In older species, such as fish, the archipallium makes up most of the cerebrum. Amphibians develop an archipallium and paleopallium, whereas reptiles develop an archipallium, paleopallium and a primitive neopallium.
In humans, the archipallium makes up the hippocampus.
