Tau² Capricorni (τ² Cap / τ² Capricorni) is a triple star system in the constellation Capricornus. It is approximately 1750 light years from Earth. The system has a combined apparent magnitude of +5.24. Because it is near the ecliptic, τ² Capricorni can be occulted by the Moon, and also (rarely) by planets.

The primary component, τ² Capricorni A, is a blue-white B-type giant with an apparent magnitude of +5.8. At a distance of only 0.34 arcseconds is the second component, τ² Capricorni B, a blue-white B-type subgiant with an apparent magnitude of +6.3. These two stars orbit around their common centre of mass once every 200 years. A third component with an apparent magnitude of +9.3, detected by studying the star during occultation, is located 0.052 arcseconds away from the A component.
