Beta Aquilae (β Aql / β Aquilae) is a star in the constellation Aquila. It also has the traditional name Alshain from the Arabic term الشاهين "aš-šāhīn" "the (peregrine) falcon". This pseudo-Arabic name is derived 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 Persian, "Šāhīn" means "royal falcon", "beam", and "pointer".

Beta Aquilae has magnitude 3.71 and is of spectral class G8IV. It is approximately 44.7 light years from Earth. It has a 12th magnitude companion, β Aquilae B, which is 13 arcseconds away on the sky.
