Beta Aquilae (β Aql β Aquilae) is a star in the constellation Aquila. It has the traditional name Alshain from the Perso-Arabic term الشاهين aš-šāhīn the (peregrine) falcon perhaps by folk etymology from the Persian šāhīn tarāzū (or possibly šāhīn tara zed; see γ Aquilae) the Persian name for the asterism α β and γ Aquilae. In Chinese 河鼓 (Hé Gŭ) meaning River Drum refers to an asterism consisting of β Aquilae Altair and γ Aql.
