Zeta Boötis (ζ Boo / ζ Boötis) is a bright speckle binary in the constellation of Boötes. It also has the Flamsteed designation 30 Boötis. It is approximately 181 light years from Earth and has a combined apparent magnitude of +3.78.

The angular separation of the components is currently about 0.8" (this varies slightly with orbital period). As the separation is close to the seeing limit of most astronomical observations, ζ Boötis is often used to test the performance of new high resolution imaging techniques.

Both components, are white A-type giants with apparent magnitudes of +4.43 and +4.83.
