Zeta Aquilae (ζ Aql / ζ 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 ε Aquilae.

The primary component, ζ Aquilae A, is a white A-type main sequence dwarf with an apparent magnitude of +2.99. It has two 12th magnitude companions at 6.5 and 158.6 arcseconds from the primary. Zeta Aquilae is approximately 83.2 light years from Earth.

The system is depicted in the computer game "Descent II".
