Epsilon Scuti (ε Sct, ε Scuti) is a star system in the constellation Scutum. It is approximately 540 light years from Earth.^[7]

The primary component, Epsilon Scuti A, is a yellow G-type bright giant^[3] with an apparent magnitude of +4.88.^[2] It has at least three faint companions, two 14th magnitude stars, B and D, separated from the primary by 13.6 and 15.4 arcseconds respectively, and the 13th magnitude C, which is 38 arcseconds away.^[10]

Epsilon Scuti was a latter designation of 3 Aquilae.^[11]
