下颌角点是位于下颌骨（下巴、下颚）的外角最低点的，最后侧，最外侧点的人体标志。此位点位于下颌骨最大弯曲部分的顶点，其升支（ascending ramus）即为下颌骨的主体。

The angle of the mandible (gonial angle) is located at the posterior border at the junction of the lower border of the ramus of the mandible.

The angle of the mandible, which may be either inverted or everted, is marked by rough, oblique ridges on each side, for the attachment of the masseter laterally, and the pterygoideus internus medially; the stylomandibular ligament is attached to the angle between these muscles.
