Gamma Lupi, Latinized from γ Lupi, is a 3rd-magnitude, B-type blue giant star in the constellation of Lupus. It is also known in ancient Chinese astronomy as 騎官一 or "the 1st of the Cavalry Officer". With a telescope, Gamma Lupi can be resolved into a binary star system in close orbit. This is known as the Gamma Lupi AB system, often abbreviated as γ Lupi AB or γ Lup AB. Gamma Lupi A is itself a spectroscopic binary with a period of 2.8081 days.
This star is a proper motion member of the Upper Centaurus–Lupus sub-group in theScorpius–Centaurus OB association,the nearest such co-moving association of massive stars to the Sun.
