Aspasius (c. 100-150 AD) was a Peripatetic philosopher. He wrote commentaries on various works of Aristotle, and Libellus de naturalibus passionibus; of these, only a part of Aspasius' commentary on the Nicomachean Ethics has survived. It is notable as the early extant commentary on any of Aristotle's works.
