The internal granular layer of the cortex, also commonly referred to as the granular layer of the cortex, is the layer IV in the subdivision of the mammalian cortex into 6 layers. The adjective internal is used in opposition to the external granular layer of the cortex.

This layer receives the afferent connections from the thalamus and from other cortical regions and sends connections to the other layers.
