Wernicke's area is a part of the human cerebrum that forms part of the cortex, on the posterior section of the superior temporal gyrus, encircling the auditory cortex, on the Sylvian fissure (part of the brain where the temporal lobe and parietal lobe meet). It can also be described as the posterior part of Brodmann area 22, and, for most people, it is located in the left hemisphere, as the left hemisphere is specialized for language skills. Occlusion of the middle cerebral artery in a stroke can affect the proper functioning of this area.

Wernicke's area is named after Carl Wernicke, a German neurologist and psychiatrist who, in 1874, discovered that damage to this area could cause a type of aphasia that is now called Wernicke's aphasia or receptive aphasia.

This condition results in a major impairment of language comprehension, and in speech that has a natural-sounding rhythm and a relatively normal syntax but is largely meaningless (a condition sometimes called "fluent" or "jargon aphasia").

Wernicke's work initiated the study of this brain area and its role in language. It is particularly known to be involved in the understanding and comprehension of spoken language.

It is connected to Broca's area via the arcuate fasciculus, a neural pathway. It also has connections to the primary auditory cortex, evidence for its role in the comprehension of the spoken words.
