Epsilon Aquilae or (Deneb el Okab) (ε Aql / ε Aquilae) is a triple star system in the constellation Aquila. It also has the traditional names Deneb el Okab, from an Arabic term ذنب العقاب "ðanab al-^cuqāb" meaning "the tail of the falcon", and the Mandarin names Woo and Yuë, derived from 吳 "wú", an old state near Jiangsu province, and 粵 "yuè", an old state in Guandong province. It shares these names with ζ Aquilae.

The primary component, ε Aquilae A, is an orange K-type giant with an apparent magnitude of +4.02. It has two 10^th-magnitude companions separated from the primary by 131.1 and 148.6 arcseconds. Epsilon Aquilae is approximately 154 light years from Earth.
