The lateral pterygoid (also lateral pterygoid muscle, latin: musculus pterygoideus lateralis) is one of the masticatory muscles, a thick short muscle located in the infratemporal fossa, originating from the infratemporal surface of the greater wing of the sphenoid bone and the lateral plate of the pterygoid process.

The major muscles of mastication are the masseter, temporalis, medial, and lateral pterygoid muscles; digastric muscle is an accessory muscle of mastication. The temporalis and masseter muscles can be observed for hypertrophy and atrophy, and should be palpated for muscle texture, tenderness, and myofascial trigger points (MTrPts).

The lateral pterygoid is a short, thick muscle, somewhat conical in form, which extends almost horizontally, posteriorly and laterally between the infratemporal fossa and the condyle of the mandible.It arises by two heads: an upper (superior) and a lower (inferior).
