The Superior temporal sulcus (commonly abbreviated STS) is the dorsal one of the usually two sulci in the temporal lobe of the primate brain. It separates the superior temporal from the middle temporal gyrus and extends anteriorly until the temporal pole, with a highly variable posterior end.

Part of the superior temporal sulcus belongs to the auditory cortex and as such, it is involved in speech perception and music perception. It also plays a central role in face perception and, more generally, in multisensory processing.
